Would you also agree that production of usable energy makes most sense at scale?

With that I mean energy like heat and motion? Because so far it just hasn't been possible to generate electricity at home in a meaningful way. Unlike heat, which everyone largely generates at home.

I would argue that there has been a technological leap, where electricity generation has become possible at home now through a combination of lower prices, ease of installation and feasibility to tie in to the rest of the electrical grid. Banning this new possibility would be a shortcoming of the policy.
