The functional purpose is its ability to create money. Twenty years from now, when you need money, the oil won't be there, because I picked your fruit. Your argument falls flat on its face. Remember, you said I can't pick your fruit, and I gave you an example.
OR: I use the money I make from pumping out the oil in competition with you to make MORE money, and 20 years from now, my kids are sitting on a fat inheritance.
My land is large, but the aquifer resides only near the border of our two properties. I may be more than willing to deplete it to satisfy my needs as long as it works until I die. Again, I'm picking your fruit.
You damage me, you pay damages. Be a dick, pay the price.
Actually, just the opposite: your fish, my fish, everyone's fish. Thus, I'm picking your fruit.
Nope, Nobody's fish, until you claim them.
It certainly can. I'm downstream and fishing salmon.
Again, Unless you put a net across the stream, you are going to have a hard time affecting the rest of the river. One man with a pole don't make me no nevermind. And again, you do me harm, you pay damages.
Or you might be of the same mind as me and cut down your forest for the same reasons I did. And the guy next to us, and so forth, until there is less and less rain forest, at which point, it becomes clear we all picked the fruit of our children. It's all fruit picking, and your ideas don't really address it.
Because it is not the
job of politics to address those issues. it is the job of the people to address that. The political structure simply delineates
how. Libertarianism, and by extension, AnCap, simply says you cannot initiate the use of force to make someone comply with your wishes. That is the only restraint. You are free to use other, non-violent means to convince someone to stop clear-cutting their forest, and if they try to clear-cut yours, you can shoot 'em. If someone causes you damage through actions entirely on their property, you are entitled to recompensation.
Aside from that, libertarianism is
neutral on Global Warming, resource depletion, etc.
