Your complaints # 1-3 are a software issue that, while mildly annoying, will ultimately be resolved in an update. Creating a new guardian is literally a 15 second process.
Numbers 4-8 are because you choose to use a wireless headset from Oculus as a wired headset through Steam. Of course that's your choice, but the optimized workflow - that the vast majority of buyers use and is the primary product design - is to use on-headset apps without a PC or cable entirely.
It's also highly unfair to say "very very few things work well in VR" based on your experience. The vast majority of consumers don't care about Facebook IDs, or PCVR, or Steam libraries, or future compatibility concerns, or the other reasons you probably choose the setup you do.
If you want to judge the current state of VR for the mass market, go to the on-headset Quest store and try Walking Dead, Resident Evil 4, Walkabout Mini Golf, Contractors, Eleven Table Tennis, I Expect You to Die, Thrill of the Fight, In Death: Unchained, Fisherman's Tale, RealVR Fishing, Golf+, Moss, Tetris Effect, Pistol Whip, Red Matter, Shadow Point, or any of the other highly rated games that work out of the box.
