It would be bigger if Biden himself wants BTC to become legal tender in the entirety of the United States rather than just for a single or a few states like Arizona.
Of course it will, but definitely you and I know Biden isn't going to do anything of that sort, neither will any state in the United States successfully implement that, I wouldn't even want to talk about this, it's more or less just like raising the hopes of those who really do not understand that making Bitcoin a legal tender in the United States is almost not possible, at least for now. I'm pretty sure we'll get big news in favor of BTC this year, but this isn't one I'm afraid.
I am not sure BTC has that lobbying power just yet, or the machinery that would take to push something like a bill. I doubt this goes anywhere just for the fact that it has to play by the political rules and there is not enough momentum for it right now.
That's true, politicians/the government wouldn't support any proposal in the favor of Bitcoin as things stand, that decentralized factor is quite a lot for them to handle, it's more like, since they can't control Bitcoin, then they just have to regulate it like they are doing.
