If you think that I'm not aware of the fact that warlords and terrorists extract protection money from anyone they can, then, um, you're very confused.
The larger point should be clear to everyone though: people with money always end up paying a portion of it to those with power. If they're lucky, they pay a small portion that is used to benefit them in a democratic society. If they're not so lucky, the money is extorted to fund warlords and terrorists and they get nothing in return. The inability to differentiate these two scenarios is a principal indicator of political and economic ignorance.
I think the point is that those aren't taxes; those are fees demanded by private-sector entities. That's what tends to happen in anarcho-capitalism: without a government wielding ultimate power, private-sector entities with sufficient power can demand payments with offers you might find difficult to refuse.
