I'm sure it makes sense as an individual in some areas for rooftop solar. But it isn't an efficient use of dollars, particularly when you factor in all the tax rebates, incentives etc. Then you have the costly controllers, wiring, difficult installation etc that make way more sense when installed at scale. You also have the advantage of a utility being able to predict generation and adjust the grid as necessary.

There are no shortage of studies that show this. So if we have limited dollars, it makes more sense to not pay home owners to do this, and instead spend the money at grid scale.
The drawbacks of course are the need for larger transmission lines, but most of that exists through cities already. You also need land, which is the biggest issue in some areas, not at all in others. But warehouse roof solar probably makes a lot of sense in that regard, since warehouses are large power consumers, are usually clustered in an area, and have loads of flat roof area.
It also threatens to increase the wealth gap, while wealthier people managed to get a subsidized system that may even make them money, while the poor have no ability to access that and will end up paying higher electricity costs to offset the added costs.
