If I build a house, I should be able to rent it out, and not sell it if I want to keep it. If the market demands builders to sell it, some will find a way. There's no intrinsic right to forcing people to have an option to buy.
If I make something that requires tedious upkeep, and will hurt my reputation if it breaks down, shouldn't it be ok for me to say, "I'm only going to rent this to you, and will take care of the upkeep myself."? (Example: A piece of machinery in a factory)
Uber is selling rides. Should they be forced to sell cars too? (ok, that may be a little stretch, but it's along the same line of thought)
If enough people want to fully own cars and trucks, they'll go somewhere else and drive JD and GM out of business.
