You’re right from the point of view that removing those with immense power from their billionaire wealth will be replaced by someone or another group. It’s our natural human condition to always want to be in control and there will always be those among us that will want more power and more control than others.
Removing the ability of any one person accumulating enormous amounts of wealth just levels the playing field. If those with a higher need to want more power don’t have the ability to control an entire sector, an entire region, an entire community or even an entire nation than others will have the ability to challenge them and regulate their power and control.
As it is now, when we allow individuals to gain enormous amounts of power, no one has the ability to challenge them. When those with enormous power decide to affect governments, industries, society or finance, there is very little any one can do to challenge them. Sure we can band together and take billionaires to court … but it comes down to how much money you have … the ability to challenge power means you need money and whoever has the most money has the most power. It isn’t a justice system that treats everyone fairly, it’s a legal system that favors those with the most money.
Outlawing billionaires won’t create a utopia, it won’t remove our conflicts we have with each other. What it would do is level the playing field and distribute power among many other people who would all challenge one another as to what they can or can’t do. It would create a more democratic system where power would be spread to more people.
Once we create that distribution of power, we could then spend our energies solving the problems we have with each other and our world, rather than in spending all our time trying to defend finances.
As it is now, democratic power is impossible because power is only centered on those who have the most money.
