Near as I can tell, you literally never even read my comment.
Consider that I explicitly stated:
* They build their own ... planes
* They build their own ... off grid power system(s)
* They ... water proof EV's to drive across harbour floors
and you responded that "No, you’re talking about building structures. I’m talking about assembling a bomb."
Let me remind you that aircraft are bombs, off grid power systems are bombs, water proof EV's with battery packs large enough to drive 7 km's underwater have the same issues you're talking about.
You apparently didn't pause to read the content of my comment before launching into a "Yes, but ..."

I've already linked to locally built ground effect plane (with builders plastic for wings), here's a locally built EV: https://www.abc.net.au/news/2023-07-30/nt-world-record-darwi...
Average people are quite capable of doing extraordinary things and not burning down their houses - you just have a low opinion of "average".
Idiots that can't read manuals and installation guides should avoid house grade battery packs, sure.
