But now you're attacking a straw man version of TFA, which is saying "sure, hardly anyone wants to run their own servers, but enough people do, and that's all you need for a suitably distributed infrastructure".
Not the parent you're replying to, but I disagree with the assertion in your summary. I don't think the "enough people" here actually is enough. We're talking about a small fraction of a percent of all internet users. I don't see how that could be enough give the non-server-runners the touted privacy, security, censorship-resistance, and data-ownership benefits of decentralization.
