Great, you can point to some that haven't been hacked, exploited or just plain collapsed yet.
You said "day traders on FTX are learning first hand the value of DeFi", but DeFi is just as much of a shitshow as the rest and has had just as many collapses.
Uniswap, AAVE, MakerDAO traders will disagree with you.
I am one of these people: I had funds locked into a CEX, was lucky to pull them out some days before turmoil but others not so lucky. During that time my DeFi holdings were fine. I would now rather take on protocol risk of something established and proven like Uniswap, instead of risking with an unregulated CEX.
Hardly says that DeFi as a category is reliable.
