I agree with all those things, and some of them are already in place (the 20 mph speed limit on paths comes to mind immediately). We have speed limits, and rules that say 'max speed should never be faster than what is safe for conditions' which covers every conceivable scenario you can think up. Also, cars have no class system and speed limits work just fine.
But we don't live in a world where many don't seek out every opportunity to wag their fingers at you, or make new redundant laws. Also think for a minute about the state of the bicycle manufacturer and retailer world when ebike laws were introduced. The laws we have now in part became what they are via bicycle industry influence to tamp ebike use down (this being before the industry figured out they were here to stay, and how they could make money off of them).
Now that the mainstream industry is thoroughly invested in this game, and the ebike using population is on the way to making them ubiquitous, we'll slowly see a shift away from regulation (no less than a decade from now). Remember it took decades for derailleurs to be accepted as not being a dishonorable cheat. In the present day that viewpoint is so far off the mark its hard to even credit as being true.
In the meantime, there will be whining. So get out your earplugs.
