this fact does not matters since if people valued bitcoin at 120k then bitcoin price would be 120k simple as that also pump and dump scene exist in stock too, does this stop people trade in stock??? I don't think so
Sure, but the people who value Bitcoin at 120k and have the power to move markets aren't average people, they're banks, investment firms and billionaires. In a system that was supposed to be decentralised and fair, it's still the same players with the most power, access and early information who end up with the advantage. That's the problem.
You asking decentralised power that everyone can have "fair" power level, that not exist
