We don’t really do this because there’s no concept of ownership of food to that degree. Maybe 200 years ago, where a farmer may chew you out since he toiled the soil to get you that carrot.
So, for us to not be possessive of knowledge, we’d need to evolve. It’s not likely in our lifetime, but perhaps 500-1000 years down the line the social fabric will evolve to handle this, similar to food possession.
Or I could be wrong, and we just have a bunch of naturally thieving crooks all over the place.
