It's not always about censorship resistance. What if someone uploads child pornography on IPFS? Do we all just go "ah well, it's immutable" and live with it?
Like I've said elsewhere, this is "for better or for worse," depending on your political sensibilities. Again, I think Tor is a good example here. Lots of CP on Tor, or so I hear. But also persecuted journalists and whistleblowers, and safer drugs than you'd find on the streets. You can't realistically say "I want X to be outside the reach of tyrannical governments, but not Y." It's an all-or-nothing deal. By its very nature, these sorts of libertarian technologies will attract all the illegal parts of society -- for better or for worse.
Having used both defi and traditional financial infrastructure, defi definitely feels a lot, lot more frictionless to me, at least while acting within the Ethereum ecosystem. Time will tell, but I find it hard to believe such frictionlessness won't eventually force its way into the world.
