Still won't stop idiots from stealing or inheriting them.

As for technology levels... that's tough to compare.

I wouldn't say this place seems that advanced compared to my world, but I'll have to give that it's got a lot of daily conveniences that we generally don't have. From what I've seen, Earth seems to have more sophisticated methods of mass production than we have, which is probably a big reason there's a gap between us. We just can't do that with our technology right now.
