As someone who has been in this space a long time, I assure you I am idealistic in my positions. Hopelessly idealistic.

What does Ban even mean? That it is illegal to run in places like the US? Very unlikely, and as more institutional money flows into it, it grows more unlikely. Some places are starting to put 401k/pension funds into it. Some places are raising it as legal tender. There is also that 1st amendment thing.

So will it banned like drinking straws? (which are still available) Or banned like drugs? (which are still available).

I feel you WANT it to be banned because it tickles your authoritarian tendencies. I am glad we live in a world, at least today, where your wishes are ignored.
