For sure, the banks are investing in blockchain technology. I saw a post about Goldman Sachs's Circle and another one called Revolt...Visa is eager to make a move and I've heard that JP Morgan and Chase are investing/financing ETH.
I'm all for people making investments and making money off the best cryptos out there but we need to be very aware of the attempts to infiltrate and control certain blockchains.
I think they will indeed start to steer things in a new direction. You're analogy of buying at farmers markets is perfect. Power to the people.
