Doesn't lose them money, the used game woudn't make them money anyway which is why they lobbied to try and make reselling used games require a royalty or be illegal for years before everything became digital.

As for emulation they lie and call emulation itself illegal (the copies may be but emulation itself is not) because then they can't pull a disney and "vault" old games on their digital storefronts and make you buy it again when they decide to just up shut down the previous server when they launch the next console.

They don't want us to own the things we pay for. They want us to rent them while not realizing it.
