Can’t you say that about any period in time where technology was able to progress relatively uninterrupted?

Better technology will always result in creating more output with the same or less inputs. Not only do we get more output (wealth) but we get higher valued output, which is only made possible by the lengthening of the production process. We were able to increase wealth in the aggregate in spite of fiat theft in the last 100 years, but we would have been better off without the theft in the first. But even if that was not true, growth achieved through immoral means is still wrong.

The discussion should start and end by acknowledging that stealing is bad.
