All those components are set up so that they function a certain way, more dangerous versions are restricted

TY for making my point for me, it was really nice of you. Legalization is what allows those manufactured safeguards to exist. Without legalization, there is no way a company is going to sell a still that meets a UL safety metric. Which in turn causes anyone who wants to do this to use a cobbled together rig that's probably leaking fuel or gases.

Lots of things that are dangerous are banned or restricted

And lots of things that are dangerous are not banned or restricted, and are in fact extremely normalized. I could go buy fireworks in a tent on the side of the road, without needing to provide my age or any sort of training -- and fireworks are VASTLY more dangerous than distilling.

Dude distilling 5 gallons of wash with no understanding of how it works, the danger to him or his neighbours, no regulation of the parts or ingredients that go into his setup is a menace and an accident waiting to happen.

Again, this is a product of prohibition and not having access to safe equipment or information. The cost/barriers to entry for home distilling are also very high. There is a minimum amount of research that you would need to do in order to understand what the procedure is and what equipment you would even need.

Finally, I will once again state that the dangers of home distilling are extremely overblown. When New Zealand legalized home distilling there were zero reports of methanol poisoning from home-distillation, caused 0.14% of residential fires, and 0 deaths. 1 2 3.

Someone is literally more likely to have a fire and/or die from an unattended candle.
