Of course they don’t. No one HAS to do anything.
What I am saying is that scalpers are first taking advantage of buyers by artifically shrinking the supply of tickets and then raising the prices, and are taking advantage of the performers by profiting off of their work. This is why it is illegal in many places and why much stronger measures are being taken to prevent it.
Thank you. That was my first point, to which you replied "Bullcrap" .
Scalping was illegal in most jurisdictions long before the internet and online ticket sales. The principal reason that it is illegal is stadium owners have a bigger and more well oiled lobby than scalpers.
