The thing is , that side of things in practice, isn't really decentralized. Where do you buy and sell those "shares"... exchanges (e.g. binance, coinbase, bitfinex etc), which essentially just replace the centralized stock exchanges and banks of traditional finance. Whilst it's possible to avoid those, I'd guess it's beyond many participants to do technically, so the exchanges become defacto centralization, and instead of regulated stock exchanges that operate in the same judicial location, in many cases these exchanges explicitly try to avoid regulation or accountability.
