The internet is built on scrapers though - Google is a scraper, and an opt-out one at that.
Similar to saying world hunger would be solved in everyone who could donated $100 to those in need. Sure it may be true but foot stomping about why isn’t it organically happening is missing the point.
But, because this person could be anyone, anywhere your words are hollow and empty. You are impotent to stop their future actions.
The internet is not a society. The internet is all societies. Hell, more and more it's not even human societies.
And may be or could be part of the solution by them taking upon themself to implement it in an ethical manner by having the bots and scrapers respect robots.txt; unless the spec specifically says not to in that case I agree with finding new clients or another job
