The point most people miss about the US legislation is the fact that they are trying to legislate it.....which means they formally recognise it as an asset class. Crypto is not going away, and for the first time the US government have accepted this. When I first got into this space in 2016, the Government didn't even acknowledge crypto and if they did they said it was basically a scam purely for illegal activity and will be fall apart soon (5 years later, here we are).
As for the bill that went through parliament without the needed amendment, it will have a much tougher time getting through the House. Also, the crypto lobby behind the scenes is incredibly vocal and strong - there are senators and lawyers all over this behind the scenes. There is serious money behind crypto now. Lastly, any bill that passes the House will not be enacted until 2023, so there is plenty of time to educate the boomers in government by then.
They will realise their rookie mistake - ie. when you have climate concerns you don't tax PoS systems while promoting PoW systems that are the ones that actually have energy emissions (though even the adverse climate effect of those is debatable, when compared to the energy emissions of traditional finance/office infrastructure today).
Not to mention, Yellen has actually now reversed position with support for the amendment.
And also worth noting that in an absolute worst case scenario - any innovation that is driven off US shores by myopic regulation will be happily embraced by any number of other crypto friendly countries. The crypto genie is out of the bottle gentlemen, there is no going back.
