If you are going to ignore the example I gave you, while asking for examples, I am going to assume you are arguing in bad faith. So do your own homework, I'm done with you.
Again, begging the question: you still accept the theory that it is enforcement of rights that motivates people to create. You just shift the goalposts a little by saying that there are enough honest people to make it work.
The simpler model is that people like to create things, and given decent access to creation, enough people are willing to pay that this is a viable living for creators. The commercial artists who experimented with a low-threshold access to material (by not enforcing copyright) showed us empirical data that this is in fact a more likely explanation of reality.
This study merely confirms what people like Eric Flint already told us 16 years ago.
The problem we have at the moment is that we have this bizarre situation where the law says creators have certain rights as an incentive, and a lot of people do create and share work on that basis, yet actually enforcing your rights is impractical in many circumstances so there's no real deterrent.
Logically speaking you're begging the question here: if people can't enforce their rights, you can't say that the expectation of enforcement is the basis of their creative activity, because if they really couldn't enforce it, they would not do so in your view. And yet we see creative activity everywhere.
So you'd have no problems citing a source for that, then? A photo of an epipen showing an expiry date of 2021 or something?
Epinephrine degrades steadily with time and expired doses are not as effective as fresh ones. I've not been able to find anything to suggest a 5-year shelf life for an epipen anywhere, so if you'd be so kind...
Ibuprofen isn't quite the same thing. Most drugs absolutely lose potency over time, and in the case of common over-the-counter analgesics that's not a huge problem since, at worst, you'll be getting a slightly lower dose than the label indicates. No big deal.
But in some cases, like with adrenaline shots, a lower than needed dose could be fatal.
As with food, "expiration date" is usually another way of saying "sell by" date - it is not a magical date when the food becomes inedible, but there are legal requirements to not sell food that is old to eliminate the possibility that spoiled food is sold... completely different from the rationale behind putting expiration dates on medicines.
It's my non-expert understanding that epinephrine has a short shelf life, and that the dose is fairly critical so using expired vials/doses is not really an option... the recommendation is that Epipens be replaced after 12-18 months but apparently the vials/normal syringes only last about two months. I can only imagine that in a system like this, the exposure to oxygen would shorten it even more.
So you'd probably need to replace the syringe and dose daily, or every other day, for both dose freshness and sterility reasons. I'm sure you're still saving money in the long run but it's now a lot more effort, time and material to make sure it's ready to use...
