It’s not the same concrete you’re used to. It is engineered to do a lot of things at once - including the perfect viscosity to print from a nozzle and settle just right.
It is it’s own vapor barrier. It’s non pourous. When you print a 2” line of concrete, then give it 5” of air gap, then another 2” line of concrete, that’s the r value. You know stainless steel has a poor r value right? How does a yeti cup work?
Interior doors, you tie your jamb level into side of wall with a shim space just like you normally would. Not sure why you think that sucks?
Hung cabinets? Sure, you need to set wood blocking/cleats on the wall to attach them to.

You know floor and ceiling moulding aren’t necessary building components and are there to cover up what’s wrong with a house right?

With a vacuum between the stainless layers. Maybe you should look up how a Yeti cup works before using it a nonsensical example of why you think such construction would be effective insulation compared to existing methods.

As someone who worked as a professional finish carpenter and has set more doors in a year than you have in your life, I'll tell you right now that a raw rough opening that looks like those walls would be shite to work with. I'd frame them in or taking a demo saw to cut good flat surfaces to work with first. That doesn't get into casing those doors either, I guess you just expect people to live with gaps everywhere...

Crown and base make a home look good. Same as window and door casing. Are you serious?

Nonporous concrete? So this is the concrete we make basement walls out of now days? What ingredient is added to make it nonporous?

2" concrete would break so easy especially without rebar or mesh. Unless of course somebody created magic concrete and if they did, can they please share with Louisiana DOTD.

Your Yeti works because of vacuum. My grand pa's old house had a 5" space between the outer and inner wall too.
