Panarchism is a political philosophy advocating the peaceful co-existence of all political systems, where each individual may voluntarily adhere to the system of their choice, free to join and leave the jurisdiction of the governments he sees fit. International law would be used to settle possible conflicts between individuals having chosen different systems of government.

The word panarchy was invented and the concept proposed by a Belgian political scientist, Paul Émile de Puydt in 1860. He argued for panarchy as a replacement for "wasteful revolutions".

In modern times, some have argued that panarchism is an alternative way of presenting the same system as the one advocated by forms of anarchism.

The most common criticism of panarchism is that the concept is self-contradictory, because certain political systems reject peaceful co-existence. This criticism can be answered by placing a single restriction on the political systems who can participate in panarchy: that they must accept the basic principle of panarchy itself.

A world or region with a large number of micronations could provide the best embodiment of panarchy. Starting a nation has traditionally been very difficult because all land is claimed by existing nations, but seasteading may lower the barrier of entry for would-be founders of new micronations. Seasteading would also make immigration cheaper and easier (seasteads being analogous to mobile homes).

"PANARCHISM provides the only framework that could, at the same time and in the same country, satisfy the RIGHTFUL aspirations of all kinds of statists as well as of all kinds of freedom lovers. Since the radical freedom lovers are almost everywhere a small minority and have little chance, in the short run, to convert all the statists to their point of view, they should be the first ones to adopt this program. However, they find it very difficult to do, since they are, like most statists, stuck on the territorial model, which excludes tolerance for exterritorially autonomous volunteer communities. It is also the cornerstone for any rightful and efficient peace, defence, revolution and liberation effort, since it could turn most of the resources of any dictatorial or totalitarian regime against it and could do so without driving the regime into a corner, ready to undertake mass murderous steps. Even the worst regime has some voluntary followers and under panarchism it could retain these, as long as it satisfied them. I know of no better program to defuse and finally abolish the threat posed by ABC mass murder devices combined with popular notions on collective responsibility and enemies, all tied to the territorial model."
