There is a lot of wrong with this post, and I bolded it all out. Responding to all would take me two hours, at least, but I'll just respond to used games and "benefits for you".
For one, not everybody can afford a bunch of new games every month. People post-2007 have gotten quite a bit poorer, in the US and everywhere else. The used game market has always been around to fill in the need of poorer people and the needs of collectors. It won't go away as long as there is the need for it - and even so, Microsoft only limits the used market, they're not eliminating it. Here's a good video on the topic:
For the other, don't expect any good for the gamer out of those measures Microsoft introduces. They're doing all that they are doing to squeeze every last dime out of the consumer. Starting with their overly expensive console ($500 is a lot - but 500 Euros is MUCH more. Plus, the salaries in most of the Eurozone frequently lower than in the US), and ending in pimping the used game market. I know I probably won't convince you, but I can't miss it anyway.
Thats your opinion and only that. Many games never buy new, ever.
His is a fairly well informed opinion though. If a gamer doesn't buy new now, what makes you think they'll suddenly be able to afford new games later? They're more likely to turn to piracy as an even cheaper alternative.
The used game market allows those from middle income households to trade in games and make more new purchases in the long run. Studies also show that most impulse buys tend to be for used games as it reduces the risk, but this also improves exposure to franchises and gaming brands. Effectively, each used game customer is a publishers future customer.
