There exist many microwave ovens which are much more similar to a computer
than an old console is.
Same thing with modern cars, tvs and so on.
Since they are just machines for playing games (I didn't buy them to do
computing) and they do this just without any malicious features (which they
simply can't have), then it is ok for me to use them, just like it is ok to
cook my meal with a microwave oven.
The problem with DRM is no problem because of two points:
1. If you buy a used old console game, you don't support the distribution of
the DRM techniques, because the producer of the game does not benefit from
this transaction
2. Nowadays, the DRM restrictions don't work any more. We are able to copy
this games and share it with anyone, so it is no problem to break the
handcuffs.
