Excellent news. Keep pushing for consumer rights. Next, let's address why companies can take advantage of a global marketplace but consumers are region limited.
Consumers are region limited in no small part due to the different laws and regulations applied by each country.
It would be cheaper and more efficient for Steam to just host a US storefront (since it's based in the US) and sell to all from there.
But European countries aren't happy with their citizens just buying from a US storefront en masse. Games sold in those countries need to follow local regulations, which adds additional costs. There can be compliance issues (like language requirements, support requirements, data retention, local tax, etc.) that raise costs, all of which have to be incorporated into the local price since those costs are above and beyond the actual cost of the item.
Even getting Europe to a single set of unified laws would be a massive step towards getting rid of regional blocks.
So long as individual countries all want their say, you're always going to see regional blocks.
I'm all for the ability to sell my digital games but what you are saying is very fair. If I claim ownership of digital media it's up to me to deliver a second hand product in the same way as a physical object that I've taken money in exchange for.
This is something that consumers don't want to deal with.
If you sell a disc, you have to provide the disc. If you sell a digital game, should you then be responsible for providing the digital bits?
