The presence of government may be viewed as a precautionary measure in case intervention is needed

Assuming the 'left' will generally attempt to attack freedom and capitalism, for the benefit of the government, whereas the 'right' will leave it alone (as with the laissez faire philosophy) government might still be tolerated on a moral basis. It might not be such a bad idea to have a government with the legal authority to intervene in the markets, and so then government is tolerated for this reason. If you think the 'market' should be left alone then it is prudent to vote for the 'right wing' anti-authoritarian laissez faire (liberal) party.

The government can be retained within a moral framework as a precaution against authoritarian intervention being required, and no one being there to provide it.
