After all, you did not explicitly tell him not to do any of those particular acts. And if you do place a long list of forbidden behaviors there, why, I'm sure your neighbor's a creative lad. I have no doubt whatsoever that he can think of a myriad of things he can do that you cannot possibly foresee and explicitly forbid. The opportunities for getting what you need are mind-boggling. Currently when you die, if you were too frugal, too successful, too prudent in your life, and you amassed too much money, the State has no compunction stepping in and seizing over half the wealth you accumulated.
Estate taxes are a mere drop in the bucket, though.
Income taxes, social security taxes, Medicare taxes, sales taxes, gas taxes, sin taxes, property taxes, and on and on are taken from you whether you want to surrender them or not. Those caring folks in Texas are at least considering that small sop to your sensibilities. Then there is the draft. Once that principle is accepted, the rest is only a matter of time. No inkling crosses the benighted consciousnesses of these obscene rulers that another path exists for solving the very real problem of transplant shortages.
