Among concerns of the "poor people", who want to pay no taxes... Well in my opinion and according to historical data => Taxation has always improved standard of living and technological progress :)
However the long-term implications of a tax on every trade are much more worrisome :)
The US - currently the leader of taxation in crypto want to basically collect tax for international capital... will ultimately lead to a war about those taxes :)
Even worse - it will produce one more deflationary pressure on Crypto currency! People would make significantly less trades => even more "HODL" => Eveng huger bubble to burst at probably 30-60 trillion market cap
So not a good idea to tax every transaction, i think...
if the bubble bursts faster at around 10-20 trillion market cap, I think that should be considered as a success for humanity :)
