I mean you exactly underline what I said. You can use anything for desktop usage, depending on your requirements. But Alpine is not meant to be used like this. Or with requirements like yours, you basically could use anything, there is no really advantage of using Alpine for your specific needs compared to many other distros out there.
I am not saying nobody should use Alpine on desktop, its just false “advertising” if you proclaim its perfectly fine to be run a s such.
