Batches under a certain size don't have a problem with methanol poisoning. You need a large enough batch that you get a high percentage of methanol in the "heads". Usually for batches under 100L, it's not an issue. A sensible policy would be limiting "home" distillation to 50L batches (which is a lot of booze; hard to argue you need more than that in a batch for private consumption).

Batch size has nothing to do with it
You have no idea what you're talking about. Please Google it.
I have, you're pushing nonsense.

The methanol doesn't "come out in the heads" and batch size doesn't affect the final concentration as a % because roughly the same ratio is present during a run with a slight in crease in the tails due to the with methanol bonds with water.

Methanol poisoning comes from tainted consumables.

Interestingly, after looking at this more closely, what I said is true of rakija, which is what I'm most familiar with (part of my family is Serbian), but appears to not be significantly true for grain distillates. Your sources mostly don't address these topics though; the latter one is mainly about copper and lead levels.
Do you have any sources on methanol concentration that support your claims? If not the sources I provided show a low risk.
Stone fruits (plumbs, apricots, the two most common fruits in rakija) have higher methanol levels:
