I'll admit I'm not super familiar with this philosophy

"Do you seriously think that it makes any sense to let a person make money just from owning something?" Well, yeh, I guess I do. There's a risk and cost associated with buying that asset, so people should be allowed the opportunity to make money from that risk. Of course, not everyone does - it's not a sure thing.

How far does it extend? Does it extend to other kinds of rentals, like car rentals, or tool rentals? What about things that are kinda rentals - my business kinda rents people use of a facility and equipment for a couple of hours for a party. The vast majority of our costs are associated with buying the facility and equipment, so we pay for them using the "rental" money people give us.

Based on a little reading of Adam Smith's writing, it would seem he would object to these types of endeavors too, as he seems to feel the only labour is the source of value, so renting a chainsaw to someone for $10 for the day is.. wrong?

The worst part of this lib is that they keep coming so close to a realisation. SO FUCKING CLOSE
