Your premise seems to be that these things can only be accomplished via large corporate firms, and that everything should be accounted for according to their ledgers. But a sufficiently industrious individual could endeavor to build a house all on their own, and then sell it. Should this individual not make a profit on their labor, given that they are the owner of the firm that constructed the house?
Similarly, should doctors not be able to open private practices?
Or are you saying that the laborors should be paid, but that money lending should be banned? That investors should be unable to profit from housing or healthcare? I will say, I suppose that makes you a good christian - but a bad economist. Suppose our theoretical independent home builder wants to build handcrafted whimsical log homes in the woods. He has the skills, the market is there and untapped, it is clear his plan will work - but he needs money now to buy the land, tools, and materials to build the homes that people want to live in. I have a stack of cash sitting around, and could front him that money - but its my money, and I want to be paid for its use. Just like the independent home builder would fairly expect to pay a fee to rent a tractor to level the land, he can equally expect to pay a fee to rent my money. And if he refuses to pay such a fee (or is banned via a law against it), then I won’t lend it and he will not have the funds to build the homes, so he is deprived of a job and potential buyers are deprived of their whimsical log homes.
So who exactly should not be profiting here?
Right, I understand what you are saying. What I’m saying is - that’s dumb. I’m then explaining why I think it’s dumb, and giving you the opportunity to contradict me.
This is how someone says they know they’re wrong but don’t want to admit it.
