These two points are astute, and worth noting:
You currently give up your gun rights in all sorts of situations no matter how much money you make or are worth... courts, airports, federal buildings, etc.
I give up my gun rights about 40 hours a week it costs the company $26.27 an hour.
Most of the folks here are frequently stripped of their rights, albeit temporarily, when they go into government buildings, fly on airlines, go to sporting events, concerts, and go to their employer, making a lot less than millions of dollars, etc.
So we ALL have a price, regardless of the chest thumping.
There is short term loss/sacrifice for long term security... People can say they wouldn't take a pile of money, but I would be astounded if presented with $10,000,000 that every single one of us would go live in NYC, LA, Chicago, etc. for a year or three - and laugh all the way to the bank afterward. The financial security, and being able to buy a reasonably big piece of land, mansion, provide a lifetime of financial security for your family, buy every gun you've ever wanted without even thinking twice... never having to work again, so you can spend time with family, friends, and on hobbies....
I don't think many here could honestly turn that down. But I could be wrong.
