Definitely one of those ideas that would 100% work in theory but never in practice. The concept of "voting with your dollar" is still a powerful tool because it doesn't need to be complete, just enough to hurt the industry.
Since force is a clear crowd favorite: What would that look like? Angry mod surrounds home of billionaire and guillotines them on their lawn? According to Forbes there are currently 735 billionaires. That might take some time.
The fact @auk made that mistake twice is certainly telling.
