Catastrophic fires are also an issue with deep-frying turkeys, and in fact with deep-frying anything.
And we do already have a well-formed body of law dealing with responsibility for fires, damage to neighbour's homes &c.
'Someone might maybe do something wrong' isn't really a good reason for there to be a federal ban on most behaviours. I'd be much less incensed were it at the city or even neighbourhood level.
While distilling is heavily regulated at the Federal, state, and local levels, the Feds did not ban it due to concerns over fire safety. Rather, a chief reason is "to protect the revenue," which, in the case of Federal excise taxes, is substantial. ($13.50 per proof gallon; a proof gallon is 1 gallon at 50% ABV.)
The Feds don't really concern themselves with fire safety. Rather, just as you desire, that's regulated at the state and local level. The TTB outlook is that you have to satisfy the local and state levels as far as fire safety is concerned.
The cost of 1 gallon (3.79 L) of 200 proof ethanol was $8. You could dilute this with 1 part water and end up with the equivalent of vodka for $4 per gallon. It goes to show how much alcohol taxes are.
That being said, the 200 proof alcohol was pretty vile. It smelled like the cheapest vodka you could buy. I remember a few gallons going missing over the years, so somebody didn't mind the taste.
I'd have a problem if someone was doing that in my building (and they'd be violating the terms of the lease if they were).

Which is why chip-pans were the biggest cause of home fires when I was growing up, and nowadays no-one has them.

Sure, I don't think it should be illegal. But it's bad advice.

Well, sure, but if you live in a multi-tenant building, you won't have to mow a lawn, either. These days, though, a battery-powered mower is just as good as some gasoline mowers. Not having to deal with gas and oil is a large bonus.
If that reason had anything to do with the law, it would be a fire code thing.
No, the real reason is a coalition between moral purity (left over from the temperance movement) and revenue protection. Ever heard of "Baptists and bootleggers"? Same thing, except the bootleggers are the government.
I mentioned fire in relation to a "problem" with home distilling, not as a legal issue, although fire codes related to distilling are quite extensive and restrictive.
I also mentioned the revenue issue in several other comments.
The so-called "moral" issue is generally only relevant to consumption, not distilling, and only at the state level or below, where some states have "dry" counties and other restrictions on access.
But the only reason you need a federal permit for making the fuel is so you don't go making any demon rum on the sly and avoiding the tax.
In a clean, well-controlled fermentation vessel, as one might find in an open commercial operation, this is not a problem. But when the process is outlawed, and the producers have to hide, often in places that cannot be biologically sterilized, this problem could occur more often.
But then again, it isn't really about public safety, but about people who want to control other people. Otherwise, the law would mandate adequate fire protection for steam distillers and establish upper limits on non-ethanol fermentation products in frost-distilled products. Either could address the safety concern without outright banning the practice.
In reality, I think the likelihood of a "freezer bust" and consequent punishment is pretty low. Moonshine busts are generally carried out on the state level, and the typical charges are possession and transportation of untaxed spirits.
150 proof is a highly flammable liquid. The vapor is flammable. If you have a vapor leak it can ignite. The flame is invisible. In other words, it's not something to take lightly.
In the micro distilling industry, I personally know of a half dozen fires over the past couple years. It's easy for something to go wrong very, very quickly.
