In the modern world they don’t have to be. I’m not sure a bubbling still in every home is a great idea but they won’t be wood fired so that’s a start. You could also test alcohol cheaply these days for the poisonous alcohols.
Having said that, fake booze in Thailand has killed and blinded people so it’s not risk free
That’s because they adulterate it with methanol. Methanol can be derived from natural gas cheaply. I wrote a long comment above about why this isn’t a risk with home distilling.
The much bigger danger for home distilling is fire, as you have open flames and combustible vapor. The fire codes for a distillery are very strict.
