LOL. You seem to have a fan club! If you can have gotcha moments in a discussion of tax and social policy, I'm not really sure you are discussing them at all. But obviously your conclusion does not flow from your premise. I can agree with all of what you said and still think that other values come into play.
You don't like liberalism, but it seems to me that the estate tax is about as radically individualistic a tax as there is. Everyone is treated as an individual whose primary duty is to the state. When they die, they are treated as an individual (rather than a family member) and their assets are first and foremost the state's, to be put to the state's end. I think its fine that the State takes its share, but I don't like the double-nature of the estate tax. I think of it more like the tax entering the family, and should not get taxed again if it stays in the family.
I think that there are other institutions--family, Church--that proceed the State, and I favor a tax code that does not automatically place the State ahead of them. So, for example, within our system I support exemptions for gifts to family members, homestead exemptions, and some charitable exemptions.
I don't like estate taxes because people should be able to think of the family as an economic unit, and if they have worked, payed fair taxes, and then deferred enjoyment and saved assets for the long-term benefit of their family, I think that is a good thing. A wealthy, independent family is not a threat to society.
In the end, I tend to think a modest combination of income, property, estate, and consumption taxes are fine. But my overall desire would be a simple tax code with limited exemptions to aid families and small businesses, with slightly graduated tax rate, and reduced overall spending.
