Make it expensive to change the weight of a product.
The President literally can’t do that.
Standardize the size and weight of a given type of product.
The President can’t do that. Not sure the FDA can even do that, as just about all they can weigh in on is product safety (i.e. “does not contain more than X of any harmful substance”) and categorical definitions (i.e. “ice cream must meet this definition”). They can’t say, “all M&Ms must be this big and weigh this much”.
Require the packaging to alert consumers that the weight have changed in the last year and how much it has changed.
Neither the President nor the FDA can do that. The FDA doesn’t have the regulatory power to do anything even close to that.
Tie the trademark of a given product to a certain weight.
That’s…not how trademarks work, at all.
Look man, it’s as frustrating to me as it is to anyone, but y’all can’t just make up a bunch of fanciful, largely illegal remedies to the problem and then lay the blame for their impossibility on the President’s desk. That’s just ridiculous.
