If you’re running cables through the space in your walls, you will find a hole saw and a little plaster/paint is pretty cheap. Some kind of an access panel for the entire length of the wall? That’s a lot more expensive, and uglier to boot.

I can buy conduit cheaply. But I'm thinking make the entire wall from plastic panels, plaster was the only solution 200 years ago, surely we can do better now

Drywall is paintable. It’s repairable. It’s durable and can take a real beating. You can put new holes in it and close them back up almost like they were never there. It’s seamless. It lasts many decades. And it’s $0.40 a square foot.

What plastic can beat that?
