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.

This would suggest that using induction heating would be significantly safer and have the possibility of precise temperature control. Is there any reason why home distilling does/does not do this?
