When I think of building things with my hands I think of building a table, refinishing a dresser, building a shed, soldering some electronics. 99% of people should consider doing these things. 99% should not consider building a house. That's engineering, not a hobby. How many people have done this, 1/100000? It's beyond the spectrum of things you should DIY. You have to be a little crazy to even consider it. Most people have 40+ hr a week jobs and can't build a fuckin home in their spare time. If you have the time, talent, and money to do this, great. You are part of a tiny elite group of people.

Where I live, Western Australia, maybe 2% of adults that I know have been actively involved in building and or major rennovations of a house.
There are a lot of people here with serious trades backgrounds, many with rural backgrounds that'll tackle anything.
People here even build their own aircraft and quirky ground effect flying machines.
I've built three houses; two significant renno's (jacking up and replacing major structural elements), and one from foundations upwards.
My father's played a major role in three full builds (he's not a "builder by trade", just a former farm hand, shearer, five year navy, mining foreman, etc. type).
If it is a standard type of wooden stud home the engineering skill is basically nonexist just by following general framing patterns which haven't changed much at all in around 150 years except for not balloon framing studs across multiple floors and instead stacking floors on top of walls. Framing and layout design is probably the easiest part of building a wood stud home. Once you know how basic floors, walls, and openings like doors and windows are built they will all fit together in any combination you like and be more than structurally sound because the basic design is seriously overbuilt.
I think most people would run into the most trouble trying to follow code with electrical, plumbing, and HVAC. You can frame 95% of a house the same way as a 120 year old house, but if you go beyond 15 years then all those utilities have had constantly evolving regulations and design constraints and just because you saw it in a dozen other houses doesn't mean it will pass this years code.
If you follow IRC ( code book )building a home can be entirely prescriptive with 0 engineering. This is what I did since I'm not a structural engineer and I didn't have money for engineered plans nor an architect.
You've established that you don't know much about house construction.
OK, definitely do not build a house until you do a little bit of research on the topic.
But if the topic interests you, it's worth looking into. It's not nearly as complicated or arcane as you imagine.
In the meantime though, you seem to have very strong opinions without the knowledge to support them. If you do find a receptive audience for that kind of thing somewhere, it will be to the detriment of all involved.
