>Let’s say someone stole your life savings, would you still not want reversible transactions?
I'm sure I'd want to reverse that transaction if it could be done as a special case with no further implications, but I don't think it would change my mind about reversible transactions in general, and I make the decision to hold a currency/commodity with non-reversible transactions understanding that it could backfire in a scenario like the one you describe. I make this tradeoff in part because it allows me to have funds which cannot be accessed by anyone else without the Randall Monroe method of brute force: https://xkcd.com/538/
This is actually a pretty high bar compared to a system where a bank can be ordered to freeze your account. Nobody can freeze my crypto without breaching my physical security, and personally, I'm willing to accept a good deal of risk for that property. It's okay that you have different priorities.
Anyone who has the power to freeze your bank account without recourse already has the power to seize you physically.
The IRS, US Government, EU or whomever has jurisdiction over your local bank already has the power and ability to seize your physical person. So I don't see what's being gained; if I put all my bank accounts into bitcoin the people you're trying to guard from can still come and coerce me with a gun anyway.
Meanwhile, anybody who isn't one of the aforementioned entities cannot do this, because even if they threaten or kill me, the banking system will reverse the transaction. Thus there isn't any incentive for anybody else to try to physically coerce me, because there's no way for them to keep the money.
Maybe they can, maybe they can't. You're making some non-obvious, generally reasonable assumptions about me. Your statements are true regarding me in the present, but I don't think they've always been true of me, and I don't think they will always be true of me.
