libertarianism isn't about unrestrained greed. It's the core ideal that a person should be as free form outside influence as possible, without sacrificing the integrity of society. It all falls down to your definition of free. I consider myself more libertarian than anything else, and find myself very much in support in things like basic income, road building, and so on. I do not support any fiscal regulation on people, such as demanding they cannot make more than X money, or anything else of that sort. Freedom isn't "government has no say" it is "government takes action to ensure everyone is free to do as they want". Things like basic income are pillars of such things, where a person is free to decide a job is worth the time while knowing they aren't going to starve. Forcing companies to pay good wages, without requiring a minimum, and allowing people to work for whatever they want to, while making sure nobody gets screwed over for doing so.
