Why don't they just ignore the EU laws such as 'right to be forgotten', or 'cookies laws', or 'privacy', or 'competition', or even collecting VAT. It's not like the EU will block the domain name. Google has done that with China when China ordered it to censor certain web site. Google decided it wasn't worth the trouble to be bullied by the Chinese government so it pulled out and ignored them.
Google's China domain, Google.cn, now redirects to Google.com.hk. The new site reads, "Welcome to the new home of Google China search." The switch means Google is no longer censoring search results for its Chinese visitors. Whether Chinese Internet can actually access Google.com.hk is another matter. It may be blocked by the Chinese government. The move follows months of negotiations and threats between Google (GOOG) and the Chinese government.
Why/when don't/will they do the same thing for the EU?
It's not like the EU will block the domain name
that assumption is untrue in general, as many owners of gambling and torrent sites know firsthand.
