The other servers do cache the content for some time yes, but if your server is based in a country not friendly to your posts then you are vulnerable to takedowns as you say.

The benefit I’m saying we have in the fediverse is that you can pick a server in a politically safe area (ie outside Turkey in this case), so they are less likely to comply, especially if they are small or don’t care about being blocked by that country (that’s usually the only thing they can do unless you have an office or staff there that can be arrested - less likely to be the case if your server is run by some dude in another country).
