I get the potential existential crisis issue - but bitcoin is subject to that, because can't governments blacklist a wallet? Then that person can't effectively take their btc away, just like in regular banking, based on some on govt identifying a criminal action, people lose their bank money when it is identified (drug dealers or whatever).
Most of defi is based on collateral, and if locked collateral can be debased by censorship, the whole thing falls apart.
A good reminder as to why crappy old dumb rock ossified btc with no features and 13 years of track record and no founder is something pretty special
