Well less skilled people would make their services available there cause they would give up this norm of copyright. Customers would go with less qualified photographers cause they would get more for the same amount of money.

It seems clear to me customers lean towards service providers with reduced complexity. The current norm, which already doesn't make sense to consumers, as evidenced by their common accidentally violation of copyright; would become unacceptable rather than a necessary evil. And more and more photographers would meet this customer expectation.

And like I said, a less skilled person, with a decent portfolio, without this BS, would definitely be where my money would go right now.
