You have your designs and then you open up a building to do repairs or start construction and some surprise presents you that you weren’t expecting.

And yet, the field of architecture is still highly valuable. Without those designs, there would be a lot more problems. Try building something complex without a design. You're going to waste a lot of time and materials. My point there was that it's not like the digital world where mistakes and trial and error and rethinking things can sometimes cost almost nothing.

Theoretical design is pretty worthless until you try it out. Until then it’s just an idea or hunch you have....ignoring all the years of trial and error that built a base of experience already

Lots of (smart) people have tried lots of things, there is a ton to learn from that, you're calling it worthless and taking it as an assumption at the same time.
