The USA are freeriding the benefits of EU's regulation, sounds like they (EU) should raise tariffs for that!

(if you can't tell whether that is sarcasm that might be because I also don't know)

It's called patents and now I wish EU had patented the core aspects of GDPR. Like, "Method of requesting and receiving informed consent" and, more importantly, "Method of requesting and receiving informed consent on a computer".

One specific thing is maybe a patent, but the whole liberal democracy with laws and all that could be run as a franchise.

You will most probably get a different version of the same product (cheaper and worse) compared to one sold in EU. It takes one market participant to do this and everyone else will have to follow, otherwise consumers will buy the cheapest one.

Yes. We already get different products based on retailer (Walmart gets different versions than direct from manufacturer or other retailers on many products).

There are even claims that Black Friday products are even special runs that are slightly different to lower cost.
