Exchanges exist and advertise their services in every asset class. Do you think the whole financial system is a sham? If so I have some decentralised fungible tokens you might like.
If you think ideas can’t do good, then it sounds like you haven’t spent much time listening to anyone. Obviously if you’d considered it even cursorily you’d recognise that we need philosophy/politics/law to get beyond “sky man says bad” levels of ethics and morality in society.
“A true finance expert… like an economist” 😂
Well, a bunch of ernest and thoughtful philosophers called it effective altruism (see Toby Ord, will mccaskill, Peter singer). Then it was adopted by the deluded arrogant tech/finance bros and yeah yikes. Sucks to be a philosopher I guess. Someone uses your ideas fraudulently and boom, they’re your problem.
How about if you spend more time being an ass to people online than doing good?
