This is like the Christian ban on charging interest in theory it is doing it for a worthy cause but in practice just banning something isn't the answer because it doesn't address the source of the problem.
In efficient markets profits trend toward zero so having more traders will accomplish that goal better than banning traders. It is the same with interest, interest goes to 0% if there is enough saved capital to fund all investments banning interest makes it harder for the interest rate to go down.
It would be better if we built an economy that can handle low amounts or even zero profit by eliminating the dependency on yearly growth.
