To be fair, many of the problems you just described are specific to console games. But more specifically to your point this service would actually eliminate the need to keep the game up to date, as the centralized server would maintain an update product. So this might actually improve your game experience, as you would never have to wait for an update again!

Plus it runs in chrome so you don't even have to worry about installing/tweaking settings/finding the disk anymore either.

This will be adding those problems (centralization of services, recurring costs to play your existing games, and to play multiplayer) where they don't already exist.

PC game companies are already making single player games that run on your local machine require an "always-on" network connection to "thwart piracy".

I've posted more above, but I have also posted this yesterday detailing why these multiple-clients-required games can and will personally sting you, and are a benefit to absolutely no one: https://news.ycombinator.com/item?id=18111288

tl;dr: steam doesnt tell uplay you own the game, uplay uses a separate key, it takes days to go via tech support to fix your game, or just minutes to pirate it. Google is going to amplify this already crappy situation.
