There is no need for some kind of organization or political force to take in charge, we don't need a central force that is gonna say what do we want and not want, because it can't represent the majority of the bitcoin users, because bitcoin is decentralized and that is the it should be, because one you have someone who represents it it turns to fiat that is represented by the government. and that is why bitcoin is free and should stay that way.
There are groups trying to become a party, Look at Elon.
You don't need a political party anymore because there are already politicians supporting Bitcoin. You can see how they are protecting our privacy when a bill is supposedly passed to the senate, it was objected to by some senators. When countries like are now considering Bitcoin to be legal tender, it's already winning.
