I think you misread the comment you're replying to.

People are not entitled to ignore all externalities that cause discomfort to others. For example, creating toxic pollution that spreads to people around you and forcing them to pay the cost of cleanup is not OK, but you're suggesting it is? If you were affected by this kind of pollution, would you just shrug and say, "It's OK for them to ignore this externality?"

And the part about not paying for public goods that you use, you seem to have misread as "not using public goods that you don't pay for".

People are upset with the AirBNB guy in the article because he's causing problems for the neighbors, and profiting because he's ignoring regulations. It's profiting off the backs of other people, so he's more like a leecher than any Ayn Randian hero.
