Nope. That's entirely untrue when the bots are buying all the remaining product. That is where it becomes harmful to both consumers and producers and is no longer "free market" because consumers are now being harmed by being forced to pay more for the same product and the seller is also being harmed because they are getting not even one penny more. When the price of these things are being fixed by contract (as is the case with quite a number of retail goods), then an alteration of the price caused by botters really isn't particularly different from front-running.

If something is merely priced incorrectly, then someone else can also produce that same good and charge more for it. As a reminder, snatching up everything through automation is not "producing a good", it's market interference.
