To me there are a few factors that create value. First off and maybe the most important to me is a transaction that can't be reversed which is nearly instant.

Picture this, a vendor is at a trade show. Customer comes up and purchases an item with a credit card. That customer (in the US) has 30 days from the date the statement is issued to dispute the charges for just about any reason. The second there is a dispute the vendor has the money taken from their current pending payout or taken from their checking account if there are no pending transfers. Until the dispute is resolved these funds are tied up and without very strong proof the credit card company will side with their customer, the buyer.

Same vendor sells an item for Steem and has an nearly instant transaction that is irreversible. Payment is done and is as good as cash.

Now this transaction really leads to my second point which is trust. The value of trusting that each transaction that is broadcast on the blockchain is there and can't be changed adds so much value to those who use it. When you can adapt micro payments for data pulls or license usages or so many other things and know that the payment is instant and final that trust gives so much value to the blockchain that can't be achieved in current billing/payment methods.

Not sure if this is what you are looking for, but as a vendor who has taken crypto payments, credit cards, paypal, and so many other forms of payment I can say Cash is and always will be King to me, but a payment processed instantly on a blockchain is right up there.
