Which is a fine argument, but people often don't consider that this kills off all the businesses that rely on those adtech companies. I think part of the problem is that it's not immediately obvious that sites like Google and YouTube only run because of that adtech.
They only rely on ads because that's the path of least resistance. If the GDPR eventually means that there is no Google or no Youtube anymore – which is not very likely – that just means the cost of Google/Youtube doesn't justify its benefits, assuming markets work at all.
