So you are saying if not fo scalpers, then organizers would charge the same?

Technically they could charge more. Clearly the market is willing to pay more, else scalpers could not exist. But it would require more work by the organizer to get the tickets sold, and that extra work would not necessarily be worth the added payoff. Organizers have way better things to do than to spend their days trying to look high and low for someone wanting to buy a ticket. It is beneficial to just get tickets sold as fast as possible, even if at a discount, and move on to more useful work. Those who have nothing else going on in life can justifiably spend their time looking high and low and capture the difference for their efforts.

And why organizers aren’t charging same anyway?

Because there is only so much time in the day. Same reason middlemen appear in essentially every industry known to man. They let people doing important things get back to doing important things rather than waste their time dealing with people.
