Either you have not seen solar parks taking up arable land or you do not understand how this type of land use makes the land unavailable to agriculture. This may not be an issue when those solar parks are built in a desert but it does when they're displacing good farm land like they're doing in e.g. the Netherlands. There are experiments with less dense solar parks and those with vertically placed bifacial panels which should allow combined land use but this has not gotten beyond the experimental stage yet.

Of course it is possible to forego on using arable land for solar parks, only using rooftops and similar constructions for this purpose. Roofs - especially large flat ones like used in industry - are natural locations for PV panels and it is hard to see why one would not install them on new constructions, either on top of traditional roof cladding or in place of it. The same goes for large south-facing walls.

Wind turbines can be placed on farm land without unduly reducing land availability to farming, here the problem comes from nearby population complaining about noise pollution (infrasound, [1]) coming from those turbines as well as 'horizon pollution' [2].

I have seen plenty of land foolishly wasted on single-use solar farms. That does not make it smart. In the future those will find themselves undercut by dual-use farms that continue doing what they did before solar was added.

Rooftops will not be much that.

Deserts are a particularly dumb place for solar farms, but ignorant investors love the idea, so lots of money is wasted on them.

You could be right, and I hope you are. But, given the current state of development in agrivoltaics and such, your prediction has too much certainty.

All power to those projects, but they are really just experimental at this point. Not inevitable.
