Until then the dairy industry is going to keep using the regulation to its advantage whenever it can to keep others out of the market.
I don't know what's confusing.
1.A regulation was created to control what you can and can't put in the product called "milk" for the good of the customer.
2.The dairy industry used the regulation that was built to restrain them to keep vegan milks out of the market dishonestly using the "for the good of the customer" argument.
3.If someone can fix the regulation to allow both well regulated milk and non dairy milks then it'll put an end to this bullshit.
Where have I lost you? Just because 2 happened doesn't mean 1 didn't happen first. In fact 2 would have been a lot harder if there wasn't regulation controlling the word milk in the first place.
