Your friend just want a new bike every few years, he doesn't go through it. I have been in that place. That doesn't mean older stuff becomes unrideable and unfixable. You can find parts for nearly any kind of old/obsolete bike technology ever made in volume, even tires for odd wheel sizes that have been mostly abandonned can still be found.
