When you have a USB A socket, dongle flash drives are a valid permanent solution.

On a phone's tiny port, storage will stick out very far, snag constantly, and something is probably going to break.

So external storage is just not viable if you're going to be plugging it in for more than a few minutes at a time. And buying more internal storage won't be reasonable until someone puts out a phone where it's "only" twice as expensive as high-end microsd cards. (Right now iPhone storage costs 8x as much, Pixel storage costs 8x as much and requires buying the top model for larger sizes, and Galaxy storage costs 6x as much and requires buying the top model for larger sizes.
