If your screws never stay in after you hammer them then maybe, contrary to expectations, you don't have the right tools.
I'm not specifically anti-libertarian, I think people of that mindset have a place (frontiers, in all senses of the word), but that putting personal rights on a pedestal in a highly civilized, industrialized and often urbanized society doesn't yield good results. That said, there's problems with the other end of the spectrum as well, where the group cannot focus on the important through petty squabbles, or even agree on importance, or worse yet focus on solutions that do not yield results (all rooted in the same reason as above, mind you). Our own nature is one of our worst enemies at this point.
PS: It's a question of overhead, there are some downloading lawsuits with large numbers of defendants but they tend to be worth ~3k / person and are settled individually. With a max payout < 10$ it’s just not worth it.
If we're going to have capitalism, we should at least fix this. Natural resources belong to the commons, and capitalist should pay market rate rent on those resources, the proceeds of which should be distributed to all or be used to fund commons costs (government).
The richest people in world history never came even remotely close to accumulating even a tiny fraction of global wealth. The same goes for the world's biggest commodity corporations.
There will never be a corporation more dominant in oil than Standard Oil was in its time, and even they couldn't corner the global oil market. Oil is far easier to corner than real estate. The richest / biggest private land-owners in the world, hold a comically tiny slice of land compared to what's out there.
If you have a million farmers causing it, then it has to be elevated to a national level, as an enforcement issue. It becomes no different than if country A were allowing radioactive run-off to flow into country B's territory.
If you then say that those international bodies don't function properly, such that they can't or won't punish Indonesia for failing to stop the mass pollution that is directly harming Singapore, then that is a huge inter-governmental failure that obviously needs to be corrected.
Property rights are enforced at the government level (judicial, police, military), not by corporations. Any failure on protecting property rights, is inherently a governmental failure in one regard or another.
Not even for libertarians.
Who cares about the potential winnings from a lawsuit, in a world with no health inspectors (to pick a common "the free market would sort it out" theme), if a restaurant has poisoned your granny and she's in a coma?
