As a thought experiment: How would you solve those problems with your hands tied behind your back (i.e. you don't have a government to rely on)? Just try one - assume you're in a fictional universe and writing a novel or something.
Anywho, the problem with this trail of discussion is that you can come up with an infinite amount of "problems" and libertarians can likewise come up with a "solution" to each one. However your rebuttal would always be yet-another problem because the original "solution" didn't cater for some arbitrary corner case or something basic that you assume can only come from a society with a government.
E.g. "Your customers randomly decide to not pay you. That's also OK."
Answer: Have an escrow organization that both parties trust. Rebuttal: "Your escrow organization decides it doesn't like a certain legitimate business and won't accept your trade." Or "Your escrow organization's owner is buddy-buddy with your customer and he decides to not keep their part of the bargain". Okay - "contracts", followed with "but who will enforce the contracts", etc etc.
As a side note: A lot of the time libertarians and anarcho-capitalists don't "pick" lack of regulation out of practicality, but rather out of plain moral principle. A lot of what is considered "regulation" and "rule of law", when stripped of it's noble/protective aura, is just authoritarianism and bully-like behavior.
Without a monopoly of violence, you have 3 alternatives:
a) Multiple entities keeping each other in check, in perpetual competition...
b) One faction becomes more powerful than the rest and eventually assimilates the rest or turn them into vassals.
c) Factions decide to ally up and either assimilate the rest and make vassals out of them.
Basically, smaller fish gets eaten by larger fish. The world is just like a large prison where you have to either become a large entity or belong to a large alliance otherwise you're fucked.
We have had and currently have A, B and C, we just don't "see it" because it has an aura of "Democracy" and "will of the people". If we truly had freedom, it would be part of society, every government, the UN and considered a fundamental Human Right for individual groups of people to voluntarily group together and decide to "leave" their state/nation/entity/vassal/government/faction, and form their own "monopoly of violence" within their geographic area.
But we don't have that. We belong and are forced under subjugation to our individual governments without any say in the matter other than "voting" and "community participation". We can dress it up any which way we want, but we're forced into a relationship by virtue of birth and we have no option to leave.
