I agree, if up-to-data data was available somewhere else and free, there would be no reason to pay hackers and scrape.
You could perhaps even get website operators to "push" new data to a common crawl database. The scrapers would learn there is no value on scraping X domain because the data is available elsewhere more easily.
How about a website header with a link to a static zip that contains the whole website in one hit. The Zip could be hosted on some big public sever. Perhaps even mirrored locally for each nation.
Well this is not what is happening in practice, Wikipedia / Wikidata, OpenStreetMap, OpenFoodFacts... All provide APIs and even a full dump of their database available to download for free, but no, the stupid bots still DDoS them 24h/24.
