Obviously for consumer it is better to be able to scrape sites. It is only those store owners (greedy capitalists) who do not want consumer to know that their prices are inflated.
Another thing is looking for some information, it is better just to have a language model go around the web and summarize the data for you rather than read someone's site with white letters on black background and weird font.
If a store owner doesn't want the reach, it's their loss. IMHO no need for a DoS attack.
Individuals also, IMO, have a right to sell access to their network for scraping-via-proxy. But they should be prepared to deal with the consequences, like a potential IP ban. Most people using VPNs that resell their residential network for scraping probably don’t know that’s happening, and many scrapers are indeed doing something bad, which is why there is a disdain for the practice.
