This is a fully general argument against any progress: let’s not improve any production processes, because if we make stuff cheaper to make, everyone will have to do it the new, efficient way, which would be terrible. Just try to think of similar proposals in the realm of computing: imagine suggesting that hardware companies shouldn’t make CPUs and memory faster, because this will allow software to do more things and do them faster, which will force people to buy this new, more productive hardware, and will put out of business companies trying to develop software for and run it on old, less productive Pentium 4s.
This is extremely silly: with this attitude, we’d never have transformed our economy away from where majority people work in agriculture to where only a small fraction does, and the rest is freed to make other products and services nicer and more affordable.
