I’m not going to speak on how this could be hard to implement in other countries, but in my country selling a ticket above the price it was bought for is illegal, and as a result (maybe there is other factors in in play but) it’s basically a non-issue here
In addition to being generally legal in the US, in key markets, resale cannot legally be constrained. A venue or artist cannot legally institute policies or practices to prohibit resale.
Even if resale were prohibited or technically impossible, it will not necessarily be any easier to get tickets to a high demand event as resale is only a factor when an event has enough demand to sell out far in advance of playing.
Resale is prohibited for (some?) ticketmaster events, unless you resell through Ticketmaster, allowing them to double-dip on the transaction fee.
So, it would be hard for them to make the argument you are making. They directly profit from resale (that they “can’t legally ban”) because their ban on resale is legal.
Norway! I think it’s somewhat similar in the nearby countries, but I don’t know for sure. You’re not even allowed to add the ticketmaster fee to your reseller price, so it’s techincally cheaper to buy it second-hand
