True, but why give away what you pay so much for? just a question
Very good question and the answer is that it depends on why you bought it
If you bought it because you want to own the OG, then you're not losing anything by giving the music to others. You still have the OG for yourself
But if you bought it because you want to resell it at a higher price, or because you just want to be able to say "I have something you suckers don't", then your reasoning applies.
It all depends on what is of value for you. We all know that if it was for the music and it was freely available, nobody would pay any attention to most of the rare stuff, because the truth is that most of it sucks, and usually that's why it's rare; it is because of those rare jams you're hoping to find among the weak albums when you have listened so much to everything else, that you keep looking for those albums.
Most of the time, it is just because it is rare in OG that it is of any value. Then you can easily see which kind of motivation of the ones described above is in action...
