There are no jurisdictions where all possible information can be shared safely without hiding it.
And IMO, software should maintain privacy by default - doing something less private should involve actively opting into that. Matrix, for example, creates e2e encrypted rooms by default, and even for non-e2e rooms, it doesn't announce the contents of the rooms to unrelated servers.
If you want to publish the fact that you're downloading a file to the world, you should have to actively opt into doing so, every time - you should treat this like reporting your downloads to your Government voluntarily.

This is not what I am saying. What I am saying is that there are plenty of people in countries doing illegal-on-paper things but are largely ignored by their Governments. No one in Brazil is worried about torrenting, even though it is not legal. No one connecting to a Swedish VPN provider worries much about getting copyright infringement letters, and so on. No one in Russia is worried about downloading music via VK, a social network with more ties to its Government than Facebook with the CIA.

I don't see any contradiction between what you are saying and what I am saying.
Yes, it should be secure by default. Yes, people should be aware that anything that is not sent encrypted and securely should be considered public knowledge.
So what?
Nothing of what you said negates the fact that there is a huge number of use cases where people want things to be public (Youtube? Instagram? Basically every social network?) and that they will benefit from having it that way.
You might not care about these use cases because you are too risk-averse to use them. Fine. There are plenty of other people who are totally okay with these risks. As long as they aware of the risks, why stop them?
Worse still, between a system that does only one thing "super-privately" vs something that gives them privacy when they want it and also gives them "things where I don't care if is public or not", which one do you think people will use? Look at another post on the same thread, you have people sharing multi-GB Anime over IRC, ffs.
The point I'm trying to argue, poorly, is that implementing a feature where you can right-click and explicitly choose to download something a bit faster is... probably not worth the sheer amount of arguing for "integrate IPFS into Matrix" that I've seen at every turn, for the past few years. People largely seem to want IPFS because IPFS is their pet project, not for any particular edge that it'll give Matrix, and alternative solutions are dismissed out of hand.
Even before p2p Matrix was announced, people turned up in #matrix-dev every week and argued that Matrix should replace its existing, functional file sharing system with IPFS, but could never come up with a reason to put in the work.
Sharing multi-gigabyte files with groups of people in a public way is, yes, maybe something some people do, but if IPFS was uniquely suited for this and the integrated system was deficient, wouldn't people be posting IPFS links in rooms all the time right now, and be able to talk about why they're doing this? Then it'd be a lot clearer that this is a thing people actually want to do and maybe setting up a button to do it in fewer clicks would be worth it.
Honestly, for a "normal" homeserver it does not make as much sense as for the p2p version of it. For the "actual server" synapse, I am more interested now in the multi-home-repo that I saw posted also on this thread.

Microsoft executives in the 90s: "Internet search is a silly idea. Once you find a site that you like, you just bookmark it. Who will be constantly search for the sites they already know?"
> if IPFS was uniquely suited (...) wouldn't people be posting IPFS links
The use-case of posting IPFS to share content is mostly covered by "posting magnet links", which is basically "why people just don't bookmark the sites they like?"
There is a lot more than could use cases that can come up once your matrix node can (a) manage data by its content (b) if it could know who also has it. And these use cases can be implemented in a way that do not make other use cases less secure.
You are right though that just having people asking for something without having no real background about the underlying challenges is a pain in the ass. Barely a year of working with blockchain stuff and I already roll my eyes every time I see someone on a forum doing a "Why don't you... X?" just after reading the word in some random blog. Let's see if I find time to brush up on my Go and contribute to the multi-home-repo project.
I’m interested in what those use cases that you suggest exist are. IPFS has, so far, really not impressed me (nearly all uses I’ve seen so far could literally be replaced with BitTorrent without problems) - I don’t see how integrating it into Matrix fundamentally changes anything.
