As for resale, interesting you bring up tickets as scalping / reselling them is a major issue, which is also hostile to consumers as they can pay multiples of the original selling price for high profile concerts and events, which has led to legislation and / or industry rules that prevent resale or at least prevent it through 3rd party services so that they can manage the resale price (and take their share a second time).
Scalping is not a serious risk with digital goods. When the company can sell an infinite number of licenses, there is zero risk of a third party coming in and buying up a significant fraction of the capacity and overcharging people.
