> This is a blurry line as a sibling comment noted. If I want to start raising chickens on my property, do you take it away from me? What if I start selling the eggs from the hens to my neighbors, do you take it away from me then?

No. So far what you’re describing is personal property. It’s one thing to own a toothbrush. It’s similar to make toothbrushes for your neighbors for their benefit. It’s another thing entirely to capitalize on that, making toothbrushes a vector for personal gain; making people pay more for that formerly shared endeavor, compete to provide it, engage in legal disputes around who may provide what.

It’s similarly disappointing that the competition you have in mind is what it is. The goal in defining private ownership isn’t to distinguish it from public ownership! It’s to distinguish it from personal ownership. The distinction isn’t between state and people, it’s between people and organizations. Nobody should be put in prison for making a more efficient machinery of any kind. They should be blocked from either preventing other people from doing so, or from depriving others from the benefit of that improvement existing.
