Yes, but that doesn't stop people from adding more slots than they can realistically handle.
The skills, knowledge, and resources to produce 1k widgets is totally different than producing 1MM widgets. I might be able to brute-force manufacture 1k widgets from my garage and that would kickstart the business if that's my skill and scale estimate. I need staff, facilities and a different type of supplier if I need to make millions, and I may not have what it takes to deliver on that.
