I have seen this argument a bunch of times and I am confused by what exactly you mean. Everyone is influencing the future of humanity (and in that sense gambling with it?) What gives company X the right to build feature Y? What gives person A the right to post B (for all you know it can be the starting point of a chain of actions that bring down humanity)
Are you suggesting that beyond a threshold all actions someone/something does should be subject to vote/review by everyone? And how do you define/formalise this threshold?
