Libertarianism is a theory espoused to those with good intentions by people that have bad intentions.

It doesn’t work for almost anyone. But it super works for some. That’s the point.

The problem is that it doesn't work even if everyone has good intentions. It needs everyone to agree on what "good intentions" even means.

I personally don't fully agree. Libertarianism just doesn't work at all. It is not even a complete system from a logical sense. It falls apart when faced with basic scrutiny, or they just theorize a system that's basically the same as a central government but with a private entity name stamped on it.

It is an ideology stemming from a basic principle, but they sadly don't seem to think of the entire system as a whole.

Also there's the fact that nearly everybody's idea of freedom is drastically different and some people's freedoms infringe on others.
