I personally don't put much emphasis on the distinction between use of force by the feds vs. use of force by the states or local governments. It seems to me either we are free or we are not. The manner by which we are not free (feds vs. local authority) is not very critical.
It is a pretty important distinction. You might consider rethinking your approach. Government is a social cost, anything that needs governing costs therefore...
Start with the maxim: "That governs best which governs least"
And you get this corollary:
The smallest unit of government that can effectively manage something is the proper level of government to do so.
In most cases this would be individuals governing themselves, above that would be a head of household.
In this case of the sandwich gifting, it is a city, which is a pretty big government. Some cities also care how sweet your drinks are.
When you get all the way up to a Nation State, there shouldn't be all that much left for them to do... but democracy changes that over time.
In most jurisdictions, we've even gone so far as to put them in charge some of the most intensely personal of decisions, of when people die, through progressively intrusive legislation over generations.
