Sure but wait till gov literally wants you to hand over 3% of your bitcoin each year. That is spain now. (tho not the EU)

However, to your original point, I was reflecting today on this story below. At the time of brexit the whole avowed principle of EU was that it would never legislate on matters that could be dealt with by nations on their own (aka "subsidiarity" iirc). What the fuck happened to that?? It is openly a superstate now.
