Well, there are records of your employment history and of how your job ended, so the employer can find out even if you don't tell him/her. Second, how do you know when they'll fire you so that you can quit before? There are costs associated with quitting and you should time it quite well. Anyway, this is getting too technical.
Also, you do use services provided by the government with money from taxes. Yes, I do know about the dead weight loss created by taxes. I learned about that in Econ 101 and at this point I had a lot higher level Econ classes than just that. Low taxes? I agree. But no economist in this world will tell you that a country can survive with no taxes whatsoever.
Some simple examples of such services: national defense, education, infrastructure. They are not at the right level? True, but that is a completely different issue. Welfare? Can you imagine what it would be like without any? When you get fired from that job you don't get anything until you find the next one. Something happens to a poor guy and he can't work anymore? He dies. I am not going to appeal to your humanity now, but imagine...No welfare... thousands of beggars in the streets, sick people, cripple people, old people, dying people, no free hospitals, no free education. How the hell are you going to drive the nice car in that world?

Hey, think about it in terms of aesthetics at least. Yes, I know, you’ll tell me that people will have less incentive to not work and so on. It’s a fine balance. It’s difficult to find the perfect level of social welfare and people much smarter than you and I are still scratching their heads about it.
I don't mind webcam girls, prostitutes, either. I try to not mind anyone, in fact. I am saying that some people would not do it. And not because of sexual insecurity or whatever else goes through your mind right now. Just because they want more or just something different. And if that necessarily implies working for less money, so be it.
Oh, did I mention? All of the above is just my very humble opinion.
