Your 50-50% and the supply of bitcoin doubling is simply nonsence. After first halving, there were few who hard forked and continued mining blocks with 50 BTC reward. Where are they today? How popular is their chain ? And most importantly, did it even doubled the Bitcoin supply ?
First of all, back then there were only a few hundred people, now there are millions of people.
Harder to persuade millions of people than a few hundred (especially if we play this politics game now)
Imagine convincing your neighbors vs convincing your country of something.
The difficulty is larger with more people, because the entropy grows and you need to use more and more force to counter that.
Why do you think the trolls are banned from this forum? If they had their way, bitcoin would have already broken into hundreds of hardfork altcoins...
Everyone with their silly ideas, how stupid is this political game and infighting...
