Since you seem not to have thought of it, you can also get power from the grid at night. Or from batteries. The grid gets its power from diverse sources.
So your logic doesn't quite hold up.

I'd much rather live with a nuclear power station in my backyard, than install solar knowing I'm robbing those who can't afford it for my usage of the free grid battery.
Rooftop solar as implemented today is not sustainable, and is a regressive tax.
So the only honest way to do this is with your own energy storage - e.g. batteries. I do agree the allure of being completely off-grid sounds great, until you price it out. So I choose nuclear reactor in my backyard until energy storage tech catches up.
So are electric cars. Both are solvable problems, and will be solved as adoption increases.
