what is "informal coercion" and is it unconstitutional?

Question

name a case that illustrates this point.

Answer 1

Well, as no one else has tried it, I guess I'll give it my best shot.

I would not describe any coercion as "informal," because I would not describe any coercion as "formal," to which it is necessarily contrasted. However, I suppose government coercion, such as eminent domain or military draft, is somewhat formal. I believe both are unconstitutional.

Eminent domain is theoretically necessary, but often used unnecessarily, which would constitute "unreasonable search and seizure," or at least seizure. The military draft is involuntary servitude, and therefore against the Constitution.

Non-government forms of coercion are covered under laws of fraud, assault and battery, and various laws regarding threats.

If you are aware of a term of art known as "informal coercion," then you are probably in a better position than I to define it.
