The "tech approach" of the Norway-Sweden border is suited to the relationship between those two countries (or Norway and the EU generally). It's generally accepted, not least by Norway, that the solution there cannot be applied to the Ireland/UK border without also matching the full nature of the Norway model.
I'm a firm supporter of the principle that "Everything should be made as simple as possible, but not simpler." I suggest that you are ignoring the second part of this quote.
Our current relationship with the EU is complicated already, and any change to it will have to address those complications, rather than trying to sweep them aside and ignore them. It's this sort of simplistic world-view that led to this mess, with some naive idea that one could make the decision and the details would just sort themselves out. What a nonsense that has turned out to be.
I would therefore suggest that you give more respect to the complications. Can I also suggest that you should try to understand your own arguments first, before dismissing anybody else's.
