You have to agree, though, that it depends on the value that the minimum wage is set at? If you set the minimum wage at a senior developer level, anyone at the junior level will be unemployable.

So if we agree that at some level of the minimum wage, businesses would not be hiring someone because they cannot pay them below minimum wage - then why do you think this is not happening to some people at the current level of minimum wage?

It's not as direct as that, but certainly the more expensive labor is, the more incentive companies have for automation, which reduces the number of jobs. If minimum wage were lower, we might not see so many self checkouts at grocery stores, and instead employ more cashiers.

I'm not saying the minimum wage or automation are bad, but it's simplistic to claim wage levels and employment have no relationship.
