Does it solve scalping? It seems like there is still money in sighing up with the goal to resell. Granted this is better in that I don't have to race the scalpers.
Till the sales price matches the market value scalping will exist. The best way to address that is a vickery auction. Till then scalping will continue.
I assume scalpers are often much better at getting through a heavily contested purchase flow (eg the recent steam controller release) due to tools like bots, general experience, and being able to dedicate 20 minutes or more to sitting at a computer constantly refreshing a browser window.

It doesn't solve scalping, it solves putting everyone in a Red Queen race[0] against the scalpers.
