Private jets are typically much smaller and have a correspondingly lower potential for mayhem. Yes, there's overlap, there are small airliners and some big private jets, but overall the risk is different, so there's no reason to expect the security measures to be the same.

The Falcon 2000 she flew on this morning is about 1/3 the weight and fuel load of the SWA 737 she might have otherwise.

I'm not sure what's unreasonable about the comparison. If the TSA were actually necessary, it would seem like a huge gap in security to allow just anyone with the cash to charter a few private jets around the country.

And that 737 is in turn about 1/3rd the weight and fuel load of the 767s that crashed into the World Trade Center. That's about a factor of 10 difference in kinetic and chemical energy from that Falcon 2000. If 9/11 had been carried out with Falcon 2000s we'd be talking about good the repairs look and how you can barely tell where the holes were on the WTC towers.

I'm not calling the comparison unreasonable, I'm simply saying that the two are not the same, so it's perfectly reasonable for the security to be different too.
