You can avoid that with precheck.

This is definitely a real problem. It applies on private jets in most cases too, though.
Precheck is an extremely weird product. If the TSA checks actually had any safety impact, trying to bribe your way around them should be the biggest red flag there is. Instead, precheck is expressly allowed and actively advertised. Precheck is nothing more than the TSA letting you pay your way out of a problem that it created.
I just flew on a private jet for the first time in August. All the paperwork and whatnot said masks were required but we never wore one from the second we walked out onto the tarmac. Nobody batted an eye. Even the pilots had theirs down below the chin while flying. I asked and they said 80%+ of their customers did not want to wear a mask, so they didn't push the topic.
No I can't, I was born in the wrong country and therefore may never be trusted enough to fly unmolested in America.
There is a non-zero chance that a charter (e.g. Wheels Up or Blade) will require it. That seems to be where the bulk of the new demand is coming from.
