It's amazing how people people fail to understand that making baby formula is the equivalent to making a drug. Yes, you can make coke, meth, and heroin at home.

However, it's also extremely easy to mess it up and kill yourself.

That which can be asserted without evidence can be dismissed without evidence.

That applies to assertions of fact, not reasoned arguments. There is plenty of evidence that incorrectly produced baby formula is dangerous. There are many studies showing the narrow range of nutrition and form of the baby formula that is safe.

Yes, and the claim that there are no safe DIY formula instructions is an assertion of fact. The question of whether incorrectly produced formula could be dangerous was never at issue.

Well we’ve demonstrated that the requirements are very strict, that manufacture standards are precise and include steps not available to laypeople such as ph testing, and that the outcome of a bad creation is potentially fatal. So it seems reasonable to say it follows that there are no safe DIY formula instructions because DIY implies lack of expertise which is required to understand the points listed above.

You haven't demonstrated any of that. You've asserted it, as I mentioned, without evidence.
