This is a really ignorant thing to say. If you have a hearty revenue stream but no profit, you can tweak the model to make it profitable. Some profits aren't possible at small scales, so having revenue proves you have demand and can lead to safely risking big bucks to get to a profitable scale.
Especially in the eCommerce business where you might have a deal with a supplier. It's not unusual to be able to negotiate a higher margin the more you sell. Any single financial metric alone cannot tell the whole story of a business. Revenues are equally as important as profits.
