That's capitolism at it's best. It's kind of like a certain event organizer over here charging 180 freakin euro for a Rammstein concert while I could go to Germany or Belgium to see them for 80 (still more than I'm willing to pay, but at least 100 euro cheaper).
Festivals cost upwards of 3-400 euro for the weekend, per person when it's a more reasonable 80-200 including camping in Germany.
Regular concert tickets can go for 50 here while it may be 30 in a surrounding country...
Silly thing is, people keep buying tickets so this organizer will keep charging the prices. So, if people are silly and pay 200 to stand outside the stadium, well, that's on them.
