My interpretation is that bitcoin is not "for the man", and therefor "the man" will not like or want it. But "the man" would trade in gilded gizzards if that would make them money.
What am I missing?
Permissionless public-ledger cryptocurrencies cut out the priviledged middlemen.
But more to the point, what would stop JPMorgan from getting in on the game if there was money to be made?
Long-term, it is in TradFi's best interested to oppose the emergence of DeFi. I predict they will use common and tired arguments to push for strong government regulations similar to those on TradFi, to encumber it and add to their own value-prop.
Also, some smart contracts can and will implode on occasion and that is fine. DeFi returns power (and responsibility) to the users, but as they are not used to having this level of responsibility there are bound to be losses here and there due to technical incompetence.
