A product is worth exactly what you're willing to pay for it. If you aren't willing to pay full price for it, then you're going to almost certainly either buy it used (or otherwise at a lower price), or not buy it at all. It's a well-understood principle of economics, yet game developers want to pretend that it doesn't exist and that they can jack up the price on games and still get blockbuster sales without really changing the core content of the game they release.
Used games are not and never have been a "threat" to the industry. The only real "threat" the industry faces is developer arrogance and the resulting attrition. You see, as with every entertainment sub-industry, the video game industry relies on its customers to survive. And also like any entertainment sub-industry, efforts made to favor the developer/publisher over the customer will always backfire in some fashion. People send the strongest message to developers with their wallets, and if people are buying their games used instead of new, that sends the message to developers that their product isn't worth the entry price being asked to those consumers.
Instead of reacting to this by considering what the customers want and making more affordable products, many game developers are trying to make a call against used games and to get people to only buy new. This sort of tactic does not and has never worked. They tried to get people in the US to "buy American" in the 80s during the trade imbalance, but people still kept buying Japanese and European products. Why? Because the Japanese and European products actually suited their needs better or were better priced. It's the same thing here. People will always go where the highest value to them personally can be found. If developers want to stop used sales, they need to make products which people won't want to sell, products which they'll be willing to pay full price for.
