A basic income is libertarian in that it allows individuals to actually participate in the free market as rational actors, and puts control over use into the hands of many individuals instead of in the hands of the government.

I think eliminating the minimum wage is reasonable combined with a guaranteed stipend. However, I think you will find that "undesirable" jobs are (rightfully) paid quite well. Possibly even better than now since this system would better balance the power between employers and employees.
