Absolutely, 100% disagree. Paying customers are not a foregone conclusion. You need proof, and product guidance, and you need it early and often. I agree with you about only focusing on the essential at first. I too believe in launching a very MVP and I launched my saas service without even a way to rebill a customer, knowing I had 30 days to finish that. But the plans and subscription are essential for launch unless your product is not stable, in which case you should do an invite-only beta with your friends.
