This is fair point. Adding a little bit to it

1. There exist jobs that are not worth paying someone X/hour, but are worth it at some number less than X. For the purposes of this discussion, X is "a livable wage".

2. There exist people who work, but do not need to X to survive; retirees who just want to be out of the house, mentally handicapped individuals for whom being out doing work and meeting people is helpful, etc.

Those two points are facts.

Requiring that every job pay a livable wage means that the combination of the above two will no longer be available. Those jobs just will not exist if they need to pay that much. As a result, some subset of group 2 will no longer be able to work (this part is opinion, but seems a reasonable conclusion).

So, the tradeoff is being made to make live worse for some of those people in group 2... in order to make life better for people in a different group. That may or may not be a good tradeoffs. But just the fact that it exists as a tradeoff means that "no job may pay less than a living wage" is not a black and white topic; there's a grey area.
