In a vacuum, the ability to pick up multiple jobs and do different things would be a net gain to individuals, yes. Plenty of people would like to do different things throughout the week rather than having to change jobs for a change of pace. This also assumes it's an opt-in, so if you like working on the same thing 40h a week, you can continue to do so. Problem being, things today are indicating what is happening is not for the good of employees, but for the good of employers. Which brings with it a whole other slew of issues which disenfranchises the worker class. Which historically is a really bad idea if one's goal is to maintain a peaceful, functional society. It's why the question of "should X be able to make a livable wage" is one which has to be answered very carefully, as this question is slowly slipping into the territory of "should people who spend most their lives doing what others want be able to afford living". That's how revolutions start.
