The preservation of freedom is the protective reason for limiting and decentralizing governmental power.

John Stuart Mill, The sole end for which mankind are warranted, individually or collectively, in interfering with the liberty of action of any of their number, is self protection.... [T]he only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant.... The only part of the conduct of any one, for which he is amenable to society, is that which concerns others. In the part which merely concerns himself, his independence is, of right, absolute. Over himself, over his own body and mind, the individual is sovereign.2

I think that the Internet is going to be one of the major forces for reducing the role of government.

As it developed in the late eighteenth and early nineteenth centuries, the intellectual movement that went under the name of liberalism emphasized freedom as the ultimate goal and the individual as the ultimate entity in the society. It supported laissez faire at home as a means of reducing the role of the state in economic affairs and thereby enlarging the role of the individual; it supported free trade abroad as a means of linking the nations of the world together peacefully and democratically. In political matters, it supported the development of representative government and of parliamentary institutions, reduction in the arbitrary power of the state, and protection of the civil freedoms of individuals.
