First of all, come on, obviously I'm not saying there are left and right in EU politics (and in the national politics of EU countries), but what those left and rights are concerned with don't match 1:1 with the issues under debate in American politics.
Partly because there is a much broader political spectrum -- Democrats in the US roughly line up with, for example, the Conservatives in the UK or the CDU in Germany -- but also because it's just a different set of issues and preoccupations.
I do think it's fair to say that within the EU there is a general consensus about the importance of data privacy, and I also don't detect any resistance to the GDPR in general, or any question that it should be repealed. (That was partly sealed by the revelation of US spying on Europeans a few years ago, which hasn't been forgotten.)
Second, if I'm honest, I find the whole "assumptions about human nature" is a bunch of hokum and quite the opposite of constructive. Nothing about GDPR has to do with "obedience to technocratic elites", and is in fact about rejecting the ability of institutions which are not democratically accountable to gather personal data and monitor people, or make decisions that affect their daily lives, without their informed knowledge and consent.
GDPR is not a "power grab" (hah!), it's about distributing the power that comes from control of information more evenly. The EU has a lot of flaws, but this is one of the most democratic and equalizing bits of regulation that they've produced, and frankly the concessions it makes to large companies are huge.
I don't accept the argument that to be in favor of this I must be in favor of USSR-style totalitarianism. If anything, the inefficient planned economy of VC-funded startups, with their cults of personality around founders, that want to collect data and influence populations with impunity are the petty dictators of the 21st century. Personal rights should trump the rights of corporations, and I am deeply suspicious of people who would equate the two.
But that's all making a mountain out of a molehill: most of what GDPR does is harmonize existing regulation across the EU to make it easier for companies within and outside of Europe to do business here, adds enforcement teeth to the regulatory agencies and harmonizes the penalties, and sets out in actually rather specific detail what is required to be compliant, while giving everyone years to implement this regulation.
If people don't want to comply with GDPR and just block all EU users, then that will make the internet a nicer place for us, so by all means go ahead!
