Scenario 1: a scalper takes the medium resolution image from your e-commerce website, and slaps it on a series of products they sell for their own profit on Amazon without your permission.
Scenario 2: someone buys one of those prints, scans it to a high resolution, and then makes a series of slightly smaller, high quality prints that they sell for their own profit without your permission.
Is it your contention that both of these things are something that should be allowed and the original artist has no recourse?
Because it seems like your more specific concerns about e.g. disease cures could be addressed by targeted legislation creating new exemptions from intellectual property without destroying the means of protecting income from creative work.
(Scenario 1 has happened to an artist I know, luckily with a piece of non-ephemeral work)
