I can almost guarantee that if a business “discovered it didn’t need all the people and warehouses” that it would NOT see the expected growth rates in it’s prior fiscal plans. A move to online resources for distribution requires capital spend and capital loss in different areas. Marketing budgets for example would need to increase. And, margins would fall if prices held (or dropped) due to transaction costs etc. Also, the general increase in competition in an e-com world means more spend on visibility in the market to capture share.

I think you’re right about seeing that the business can continue to run with fewer resources, but growth in the business isn’t going to happen.
