Taxation is a coercive, non-contractual transfer of definite physical assets (nowadays mostly, but not exclusively money), and the value embodied in them, from a person or group of persons who first held these assets and who could have derived an income from further holding them, to another, who now possesses them and now derives an income from so doing. How did these assets come into the hands of their original owners? Ruling out that this was the outcome of another previous act of taxation, and noting that only those assets can be taxed that have not yet been consumed or whose value has not yet been exhausted through acts of consumption (a tax-gatherer does not take away another man’s garbage but rather his still valuable assets!), three and only three possibilities exist: They come into one’s possession either by one’s having perceived certain nature-given goods as scarce and having actively brought them into one’s possession before anyone else had seen and done so; by having produced them by means of one’s labor out of such previously appropriated goods; or through voluntary, contractual acquisition from a previous appropriator or producer. Only through these types of activities is one capable of acquiring and increasing valuable—and hence taxable—assets. Acts of original appropriation turn something which no one had previously perceived as a possible source of income into an income-providing asset; acts of production are by their very nature aimed at the transformation of a less valuable asset into a more valuable one; and every contractual exchange concerns the change and redirection of specific assets from the hands of those who value their possession less to those who value them more.
From this it follows that any form of taxation implies a reduction of income a person can expect to receive from original appropriation, from production, or from contracting. Since these activities require the employment of scarce means—at least time and the use of one’s body—which could be used for consumption and/or leisure, the opportunity cost of performing them is raised. The marginal utility of appropriating, producing, and contracting is decreased, and the marginal utility of consumption and leisure increased. Accordingly, there will be a tendency to shift out of the former roles and into the latter ones.
Thus, by coercively transferring valuable, not yet consumed assets from their producers (in the wider sense of the term including appropriators and contractors) to people who have not produced them, taxation reduces producers’ present income and their presently possible level of consumption. Moreover, it reduces the present incentive for future production of valuable assets and thereby also lowers future income and the future level of available consumption. Taxation is not just a punishment of consumption without any effect on productive efforts; it is also an assault on production as the only means of providing for and possibly increasing future income and consumption expenditure. By lowering the present value associated with future-directed, value-productive efforts, taxation raises the effective rate of time preference, i.e., the rate of originary interest and, accordingly, leads to a shortening of the period of production and provision and so exerts an inexorable influence of pushing mankind into the direction of an existence of living from hand to mouth. Just increase taxation enough, and you will have mankind reduced to the level of barbaric animal beasts.
