What you just said is that the buyback rate should be somewhere between wholesale rate and retail. There is no clear cut way to figure out what it should be so regulators and politicians get involved in setting the rate.
"Sustainable for everybody" argument can be used on both sides - if rate is set too low, the solar panel owners subsidize the rest of the customers if it is set too high then other customers subsidize solar panel owners.
So the argument is not as clear as you tried to make it sound.
