How many cars do you need? How much money do you need? How many boats do you need?
What I NEED is my (everyone’s) individual rights protected, which include life, liberty, property, and the pursuit of one's own happiness. What I achieve, have, think, make, produce, pursue, own, buy, sell, trade, create, say is not your business and not your right to regulate/control/limit/allow any of that. Anything contrary to that is authoritarian, anti-human, and amoral. Yes, even if it's in the name of the "common good".
Like-minded people are free to get together and do whatever collectivist thing they voluntarily agree to. But doing this by force/law/at the point of a gun is evil.
