These proposals don't say you can't charge fees.
They say that the actual total price has to be displayed from the beginning.
If Ticketmaster wants to break down a $250 concert ticket as $180 for the ticket and $70 for an issuing fee, that's fine. But since the fee is mandatory, they have to advertise it as $250, not $180.
They still get the same amount of money but people aren't being lied to, and are better able to make smart decisions about what to buy without having to wade through a morass of fine print.
