In many communities you have a guy who cooks plates of food and sells them. While technically this is illegal with out a permit, it’s usually tolerated.

No one argues these things are not able to be regulated. Instead, per the 10th amendment, it must be left to state law since Congress does not have unlimited power and may only legislate where power has been granted to them by the constitution.
