> However, for an application with a persistent UI, I fail to see how constant page loads and navigation just because "the browser can do this" make any sense at all.

in the same way how re-rendering the screen in a 3D game for every frame does it. Or how you buy a new pair of jeans instead of meticulously learning how to patch the old ones. It solves a lot of problems even if it sounds suboptimal. It was the standard practice when computers and networks were much much much slower, therefore it cannot be that bad.

I think SPA and their entire ecosystem give some sense of optimality to purists which is probably shortsighted and wrong.
