I think for many companies at least it's just the easiest way to somehow approximate value created for the customer. When the business matures one could argue that services should gain a stronger measurement of value created for their customers and charge correlating to this.

With regards to the SMB scenario I agree - and probably it would make sense for many services to have a base bundle tier with 5 or so accounts. And then price it based on some minimum value created. But also hard to do this if your competition is offering 1 user for $2.99.
