The plan isn't "banning bitcoin".
It's to consider regulation on high-energy usage crypto operations, and then "should these measures prove ineffective at reducing impacts, the Administration should explore executive actions, and Congress might consider legislation, to limit or eliminate the use of high energy intensity consensus mechanisms for crypto-asset mining."
It's unclear why you think this shouldn't be the Administration's role? If it is taking a significant proportion of power across multiple states and affecting power prices and grid stability it seems like it should at least something one branch of the federal government should have an interest in.
