The market works as this:
I want to sell you 12 eggs at a certain price.
You want 6 eggs.
You either buy the 12 eggs, or look elsewhere for 6 eggs.
If I wanted to sell just 6 eggs, I'd have listed it at a 6 eggs price.

I don't see why anything needs to change, simply because people don't want to look and/or wait just to save money buying too many more than they want [which they can ultimately resell when they are finished].
