The advantage of space colonisation is that you can control everything - the microbes, the infrastructure, the laws, the people.

There are no environmental regulations, no taxes, no diversity policies, and with appropriate screening, no human, plant or animal diseases.

To put it simply: imagine a space colony of a thousand of the best and brightest men and women Earth had to offer, where gonorrhea, AIDS, chlamydia, the common cold just didn't exist? Where one could work without the tax burden of paying for a huge welfare state?

This is something that Earth cannot offer. Even in the most remote desert you will have to deal with the local tribes and the United Nations. Space colonies could developer free of the burden of socialism.

Interesting take. The Red Mars trilogy explored something along those lines extensively and believably arrived to what you'd call Socialism. :)
