That would be great if everyone were truly on a level playing field.
You could make that so in this shared computing scenario, but our broader world is systemically rigged in favor of some people and against others. Capitalism depends on the un-levelness of the playing field for cheap labor.
i.e. while it can be useful if prices are attached to commodities (with caveats around externalities etc), it is not a good thing that prices are attached to humans, making some people's being and work less valued than others.
