"Providing land" really doesn't fundamentally even mean anything, humans didn't create the surface of the Earth. Providing means making or doing something, like making a meal or providing medical care; "providing" land just means someone marked off a square on the Earth and so generously offers not to shoot others for making use of it. (Thinking about it - there would probably be a fiction of "providing" atmosphere and sunlight too, if there was an easy way of gatekeeping it like land area.)

In a broader context, if you mean preparation of an area for development by landscaping it and running utilities and roads to it, that's done by other workers, not owners.

The owners aren't providing tools and plants either, those are being assembled, grown, and transported by other workers, who again should be receiving most/all of the profit. Obviously you need other workers to organize all of this which requires both finesse and significant self-responsibility, much like a heart surgeon or a civil engineer, but much like heart surgeons and civil engineers I don't see a reason for them to make more than 5-20x as much as the person with the easiest job.
