The inverse perspective is that you have been forced to not be able to finance yourself and I have both theory and evidence that this is true for a non zero percentage of the population. In that sense, not spending "other people's money" was never an option to begin with.

Instead of using a framing that sees other people as parasites, I prefer to see it as a bribe to people to get them away from me and leave me alone.

What would those circumstances be that prevent people from working to support their life?
