Just curious: if I am a company, why would I care about scalpers?
The only thing I can think of would be items like a game console, where the console itself is not very profitable and may even be a loss-leader. In that case, you want as many different customers to own one as possible so you can make the money on games, streaming media and other services. But then, scalpers want to make money too, so pricing themselves above what the market will bear isn't in their interests either.
I think you pretty much explained it. Because you sell one expensive to produce product and many cheap to produce auxiliary products. You want to price the main product car, phone, printer, bicycle, stroller, pretty much any physical product low so as to get the consumer on the hook. Then you price the navigation system, screen protector, toner, light-weight wheels, cup holder, pretty much any auxiliary product with enormous profit margins. If scalpers buy up a significant portion of your initial production capacity it not only means your ultimate customers pay more and so they are less able to afford the add-ons it also means they didn't need to enter your store to buy the low margin product so you lost your best opportunity to sell the high margin add-ons.
Scalpers are necessary for an efficient market and shouldn't be discouraged by any good government, but there are plenty of reasons why a producer might not like scalpers in their market.
