Regardless where one lives in Europe (including countries where salaries are lower than those living in France or Germany for example: such as Hungary, Romania, Latvia or Serbia to name a few) yet they’re confronted with 89,99€ at release considering EVERYONE in Europe as wealthy (further from the truth since there are nations in Europe where people aren’t paid 8000€ a month, some are paid x10 less than that).
Regional pricing is indifferent in this case no matter as to their actual income, it’s weird since they count countries where Euros aren’t used (Czech Republic, Romania, Serbia) whilst people there aren’t earning high salaries, like this: a Romanian earns 815€ a month but are treated no different: a 90€ game at launch (about 10% of their wage), for some reason they don’t bother adjusting it based on a specific country.
Steam pre-empts that by tracking payment methods and using all known connection locations to try and prevent VPN hopping (If you are using a VPN to Argentina, you better have a card from an Argentine bank and hope your VPN never drops).
Places like the Eurozone simply are screwed because of the legal circumstances. If people are using payment methods other than cryptocurrency (which is not accepted on steam), it is relatively easy to find their location and charge appropriately.
As for the partial form of identity thing, it is hard to create a system that would not be subject to abuse. I believe that Valve’s current telemetry practices are not unreasonable given the lack of restraint for the user. The only expectation is that attempting financial shenanigans will have consequences, and shall be traced from that data. That’s fine.
