Excellent writeup. A few points you overlooked:
Exhibit I - We are now in the 4K era and Switch games regularly fall short of even 1080p. As more and more people buy 4K TVs, they will stop buying Switches.
Exhibit J - PS5 and Nextbox are just around the corner, and nobody will buy a Switch once those consoles are out, just like nobody bought a DS after the PS3/360 released, a 3DS after the PS4/Xbone released, a PS1 after the Dreamcast released, a PS2 after the 360 released, or an SNES after the PS1/Saturn released.
