Sure, but nothing protects you from Fascists if they want to go after you. There’s so many laws that are malleable enough that they can always come up with some excuse. You should be legally protected for doing what this person did, but they’ll still try. We’ll see if their bullshit holds up in court I guess.
It’s actually not as simple as that, assuming they’re connected to the grid. Power transmission is costly too, which needs to be accounted for, not just the power consumption/generation. Them being off-grid also isn’t really reasonable because they’d need a lot of redundant power sources and backups, which would be better as part of the grid.
They should still be paying for all this, but estimating the real cost is non-trivial.
