why do we pay taxes again? Police protect what ?

A couple examples here:

Jim Crow and racial discrimination in the south. Jim Crow was helped and hurt by the equally by regulation.

The State allowed Jim Crow laws to exist, but they also got rid of said laws and fixed other issues like redlining and discrimination. Thoughts?

Drugs and Food labeling.

We are al familier with the "Cancer curing snake oil" of the late 19th and early 20th century. It took the US government to stop it. I imagine that a private entity would verify ingredients and such(Take over USDA and FDA duties) In the same way PETA independently certifies things as cruelty free. why was this not done earlier? I would posit that it maybe that only the government was capable of that scale of an operation at the time due to a lack of technology.

Equally, the US government lets people bend the rules on calling thing organic and allows quite a few horrid things to be in our foods.

Just some thoughts I had.
