If someone can create or reproduce the same kind of work that Person A produces, then that work effort (not the work product, the work) holds less value. Person A should do something to add more value.

A similar argument can be had for something that can be made cheaper than a more expensive option. If my company makes a widget that takes 100 people to make over the course of a year, and then someone comes along and finds a way to make it at substantially less cost (not labor costs) via technological improvement, then seems like OP would similarly be against this, which doesn't jive with nearly any definition of capitalism.
