Oh, dear, let's go to this now.
Computer buying of performance tickets enhances liquidity in that market. Instant sales, the venue and exhibitor are guaranteed sales, the artist(s) are ensured of their fee, all is well. The market then is extended as buyers pile in and buy at markup, and only the original seller(s) suffer in not sharing in the markup.
Or do they? Perhaps there is a raging business in brokered resales, and the venue/exhibitor/performers are the ones most cheated, if none of them share in the markup?
HFT is pure arbitrage. Liquidity isn't the primary feature. Automated ticket purchasing is even worse, in that the systems purport to open sales to buyers at a point in time, but the truth is very few human buyers are *permitted* to purchase - the bots win.
This is a good thing, enhanced only if the law could permit bot sales when disclosed in advance by the original sellers, putting you and me on notice that we are wasting our time queuing up to click and fail. At least be honest, so I won't bother, but will know that those tickets to the concert I want to go to won't cost $65, they will cost $125. Each. No matter.
Than I can make choices in an informed manner. And know that I'm actually enriching the scalpers. Then i can choose.
