Now that tickets are all electronic and the ticket sellers operate secondary markets there is no "face value" anymore and pricing is dynamic. Not all tickets are released at once and many are offered at "platinum" prices at first.
All through the 60's, 70's, 80's, 90's and 00's concert tickets were around $40-$50 in 2025 dollars, now that is just the service charge. Just go on eBay and look at some ticket stubs then put the price / date into the CPI calculator.
It turns out that the bands couldn't beat the scalpers so they became the scalpers, charging outrageous prices with the assistance of the ticketing companies.
So stopping bots isn't as important as it was when CAPTCHAs were effective, since there is a lot less money on the table for professional scalpers to capture.
