Viola, with proficiency somewhere between beginner and just plain bad. But it’s still fun (for a given value of"fun").

Maybe Toki Pona?

Judging by the link in the OP, the concern is the possibility of ICE or other federal agents breaking in. It’s not the same as dealing with a random intruder. About the best you can hope for is to slow them down, maybe giving you time to get away or for legal assistance and the media to arrive.

Given that, I’d concentrate on making the house more sturdy: steel framed doors, steel rolling garage door, properly installed security bars/screens on windows and so forth. And maybe start with a solid masonry house.

Probably not realistic for most people, but then a few years ago I wouldn’t have considered the risk realistic either, and here we are.
