You can store energy, it's not a use it and lose it situation. EVs do this. On your second point, things that are absolutely necessary like you're refrigerator, could be on the grid but everything else isn't or it's a mix or hybrid.

Also, why is everyone only talking about what's on the market? Americans are extremely inventive, there are ways to add personal power in that could be hybrid and smart so you could control all that. You wouldn't have to make it an island but readjust your wiring to handle both. How are Europeans doing it?

I had a friend of a friend put up a mini turbine when it first started, it was mostly DIY. I'm pretty sure there could be some basic DIY ways in a form that isn't blades, that are efficient enough and could be done with recycled materials. The batteries I guess would have to be new. Still a step in a great direction.

I'm thinking more along the lines of this: https://rubinmuseum.org/collection/artwork/wind-powered-prayer-wheel-20.406 , but stacked with maybe 5 rows each depending on how much one could hold. You could add on as needed and have walls of them.

I'm sure there are local engineers that could come up with new ways other than what I mentioned that make a personal wind power as efficient as a giant turbine. I'm surrounded by Boeing people, I'll ask around.

I'm going to respond to this because I think it's necessary. Not everyone is going to want to live in an urban, 15 minute city. For example, people with families or people who need nature. The 15 minute city is a great idea for some and should be planned for, but it isn't the one size fits all, especially in America.

Instead of forcing it down everyone's throats, build for it but also make suburbia more environmentally friendly. Encourage rain gardens, natural and local ground cover instead of grass, white metal roofs if it can be done in that environment as an efficient solution, and personal wind and solar power.
