I wouldn’t confuse this incident and the solution with libertarianism or any other government system because it would take a large systematic and philosophical analysis to really arrive at an agreed-upon “what is causing this” consensus.

Annnnd from the perspective of the person you’re complaining about this is an incentive for libertarianism, you are making their life worse by enacting arbitrary rules that make you happy and enforcing those rules with violence.

And it could be that some other inane government rule made it so that they had to park trucks where they did in the first place.
