Although you have a point, I think you take it too far. Many of the worst decisions I have seen salespeople make were based on the drive to get someone to buy now rather than, say, next week. They even knew that rushing things was going to be bad for the customer, but the salespeople's interests didn't align with the customer's.
If you pressure someone into a sale now and they decide to leave soon afterward — perhaps even demanding a refund or issuing a chargeback — you've probably lost them for at least a year, and then the company is worse off than if you hadn't made the sale at all. But if you take a little while to make sure you get it right, the lost week or month will get canceled out by how happy they are with what you've given them.
So you're absolutely right that, all other things being equal, a sale right now is better than a sale tomorrow. But all other things are not always equal, and if you try to force every peg you find into that round hole, you're just going to end up with a lot of broken pieces.
