I agree with them but the "makes the rich richer part" is a poor argument against something. It just means "investments promote some sort of growth that scales"

I agree with them but the "makes the rich richer part" is a poor argument against something. It just means "investments promote some sort of growth that scales". That is not a bad thing in itself. If accepted as bad the exact same argument could be used against education and to argue why we should shut down the Ivy League now. Alongside other shortsighted behaviors. That "Crypto" amounts to gratuitous waste to do things worse with no attendant applications is more important. It has always long been a cult of the golden saw proposing it as a solution for everything.
