if you don't like my electrical grid, just use another one!

I've heard of this being done intentionally in many countries, as (partially) self-sustaining households cut into the profits of electricity companies. Spain is an infamous example, though they seem to have ended the practice in 2019.

Legislation introduced in 2013 by Spain’s then-ruling Popular Party made it compulsory for any individual or company to hook their solar panels up to the national grid to be metered and taxed, or face fines running into millions of euros.
