I would have thought simple antitrust enforcement could handle this. Too concentrated a market, with venues losing some of the margin that the secondary market took.
As to the ticket purchasers, so what if you have to wait in line to “buy wholesale” and the online scalpers who are eager to serve are more expensive? Will the final price really be cheaper concert venues are able to capture much of the revenue that scalpers get now?
How about no scalping allowed?
