Yes, the FAA has violated Part 91 operators in a few cases.
Indeed so...been known to happen.
14CFR91 carries with it the responsibilities of prudent flying...stubb your toe, expect consequences, sometimes not to your liking.
And yes, the FAA has ops inspectors on the watch for unruly behaviour.
They might well nail your hide to the barn door, IF you are stupid enough to land well below reported minimums.
