I totally agree with you if we are talking about preliminary market research, which also usually involves components of research into the technical investment required.
That said, the article of this post seems to emphatically say something different: that you should actively _sell_ before building. Not merely collect research, but to sell stuff you do not already have the capability to deliver, and then somehow backfill that delivery capability after getting customer buy-in.
