The basic chemistry isn't terribly hard, but producing a consistent product is going to be tricky for a guy in his basement. Theoretically nothing is impossible for a really determined guy in his basement, but in practice if the bar is set high enough you can effectively eliminate the behavior from all but the most extreme people. Ultra-extreme people already get increased scrutiny from law enforcement, so the scope of abuse is at least somewhat containable.

Drug cartels today could manufacture their own guns, yet they don't. Or at least not in mass quantities, given how many guns they purchase from the US through various means (including in some cases directly from the US government).

Gun deaths in Australia dropped sharply after the ban was enacted. Here's a Washington Post article about the effect as well. Your figures about the UK are also wrong, but that is more understandable because they changed the way they counted gun crime which made it look like it increased after the ban was enacted--including nonfatal accidents into the records that were previously not recorded.

Not true. Gun regulation is a statistical win. You can't keep guns out of the hands of the mentally ill or criminal 100% of the time, but if you work hard at it you can reduce gun deaths by a non-negligable amount per year. Look at European countries. They still have a lot of WWII surplus floating around plus plenty of guns in the hands of really hardened criminals, but thanks to strict regulation they have relatively few gun homicides compared to the US and school shootings are extremely rare compared to the regular occurrence they have become in the US.

I think the barrel and chamber aren't tracked because they are wear items that might be replaced on a gun. The receiver is like the frame on the car. You could build one a lot easier than you could build your own engine from scratch, but it's also the part that you're least likely to replace on the vehicle.

If this takes off (which I kind of doubt outside of the fringe), you could expect the government to start regulating replacement chambers and barrels as well. I would expect it to have the opposite effect that Cody Wilson is intending.

However, this just delays the inevitable. As home manufacturing improves over time, it will eventually be cheap and easy to make your own gun at home, at which point the Genie is out of the bottle. About the only thing left would be strict regulation of primers and maybe gunpowder itself.

A Mars colony would have to be mostly underground. Keeping pressure domes sealed for decades or centuries on end would be a constant struggle and you would have problems with the occasional meteorite and cosmic rays. It would be a hard life for the people there, and I would expect a lot of psychological problems in the long term. Worse, for this colony to work as Musk envisioned, it needs to have a copy of Earth's entire industrial base on there. It has to be able to build a space ship and return colonists to Earth after the planet cools (in 50k years) from the cataclysmic meteor strike that wiped out all life on the planet.

Seems like it might be simpler to capture an asteroid and mine that instead. Neither problem is really feasible in our current political and technological climate, but in 50 years who knows? The one thing we won't be able to change short of maybe Space Elevators panning out or the discovery of Antigravity is the high cost of lifting mass out of Earth's gravity.
