I like Origin Jeans: https://originmaine.com/durable-goods/bottom-game/factory-de...

Super robust, proper pockets, good fit, triple stitched, enough flex to squat in, etc. Twice what I normally would pay for jeans but ended up being totally worth it. But you do have to get used to the heavy denim feel and they'll never be as breathable as disintegrate-in-two-years jeans.

Have you gone down the fancy selvedge denim route? A lot of that stuff is overbuilt and might make you happy.

My pants could, at one point, stand on their own. I bought rather heavy denim, because I wanted to be kept warm (or at least keep the wind at bay) during the winter. I don't remember how long ago I bought them. I try to be nice to my jeans; even considering that, it's a far cry from parents' 18-24 months of use as my Naked and Famous jeans pass through grade-school-age.
