It's really pretty simple: In a state of nature, people acquire animal territory -- enough for replacement rate fecundity. That's virtually a tautology given a fixed carrying capacity. To acquire more elaborate properties, people enter into social contracts called governments. One of the key features of such a social contract is that the government provides a service of enforcing these more elaborate property rights. Think of it as a kind of mutual property insurance company specializing in theft and fraud insurance, with a strategy of creating a human ecology in which property rights are respected. The "insurance premiums" for this service -- the use fee for those property rights beyond animal subsistence (homestead) -- are the proper source of government revenue.ravingdave wrote:I am not completely certain I understand what you mean about taxing property as opposed to economic activity.
Now, the question remains: Are there any stockholders who may wish to receive a payout of dividends from the insurance company they "own" as a result of founding the insurance company? The answer is "Yes, of course there are precisely because of phenomena like the network effect that made Gates the world's richest man through no merit of his own."
The best way to estimate that founder's dividend is to take the in-place liquidation value of assets minus liabilities, assessed at their liquidation value as financial instruments held by creditors, and extract an economic rent dividend at the risk free interest rate used by modern portfolio theory (time averaged short term treasury rates). The only question then becomes "Who holds the founders shares in the insurance company which operates the land trust called the Nation State?" The preamble of the US Constitution designates the beneficiaries as "our posterity" so however that is interpreted, it is reasonable to treat it as an untaxed, multigeneration inheritance.
To apply this to Gate's fortune:
Imagine what the "in-place liquidation value" of his copyright on MS-DOS would have been worth shortly after IBM began distributing it for their first 4.77MHz 8088 IBM PC.
