As a person who scrapes sites (ethically), I think it's impossible or pretty damn near impossible to prevent a motivated actor from scraping your website. However, I've avoided scraping websites because their anti scraping measures made it not worth the effort of figuring out their site. I think it's still worth for do minimal things like minify/obfuscate your client side JS and use some type of one time use request token to restrict replay-ability. The difference between knowing that I can figure it in 30 minutes vs 4 hours vs a few days is going to filter out a lot of people. Of course, sometimes obfuscating how your website works can make it needlessly more complicated, so it's a trade off.
