That “solution” suffers from the problem that requiring hundreds of thousands or even millions of people to get informed about and agree to do something is incredibly more hard than it is for a few tens of people or maybe a couple hundred to as individuals swarm the sales venues and take all the tickets to resell them for more money.

Or putting things another way, it’s a mountain to climb for large numbers of people to organise and stop scalpers (and that, only for a while), whilst in the current commercial environment scalpers appearing is a natural outcome.

This kind of thing usually requires changing the structures that make scalping so easy, rather than hoping that somehow (magic?) hundreds of thousands or miliions of people agree to do something.
