I think that there will never be much common ground between infringers (alleged or willful) and trolls that wish to collect on infringements.
It's like the two of them being across an impassable gulf of water, with no boat.
On the one hand, we have the content owners (who are perceived to be sketchy).
They want to be paid sums that amount to thousands of times what the content is actually worth.
I think that their perception is that anyone that is "caught" infringing has to make up (pay) for all other infringements that might exist, whether real or imagined.
Of, course there's also the "greed" factor.
On the other hand, there are the alleged infringers. These people know that these photos are worth a couple of bucks at most.
If an alleged infringer is the brunt of over the top threats, or the accuser can't provide any proof, then the reputation of the retailer and/or artist is damaged.
Demanding less money from the alleged infringer won't improve results either. Unless a couple of dollars is demanded, the settlement demand will be seen to be unfair.
A "fair" settlement is probably two dollars in most cases. But, people couldn't be bothered putting a 2-dollar check in the mail.
There's a solution to the whole problem. But some people aren't going to like it.
Stock image businesses will have to sell images at a price that people will pay.
Furthermore, a bit of savvy marketing is needed to let people know that a plethora of affordable images exist in a convenient, friendly place to do business.
Now, I can already hear the hollering all the way up here in the woods.
I'm hearing, "I can't make six-figures doing that!!" and "I can't feed my family".
Get over the sense of entitlement. Tell your wife/husband to get a job. Maybe photography isn't for you. Maybe you need a better and different business model that makes money.
DO NOT expect copyright laws to be "loosened" to the point that registration isn't required, or that non-exclusive agents (retailers) can collect statutory damages.
It's not going to happen.
