I'm willing to bet this information might shed some light here .. I could see many people being fine with a high-scale crypto with no anonymity so long as the purchase is low and not really requiring the need for privacy (think groceries - not prescriptions, where maybe you only put $50 in your wallet at a time). I'm thinking this CN might fill a niche for a little bit more costly purchases because of what it offers. Honestly, I'd find it crazy to want to ever hide the fact that I bought some milk, eggs and bread from the grocery store from anyone - I just don't care about it, and why would I go overkill and permanently obscure that data when it's not needed.
This is potentially addressed with an off-chain model, even something as simple as prepaid card/account which has been widely used already to address the fact that Visa transactions don't scale down to small purchases very well (so iTunes, Starbucks, etc.)
If you don't care that someone is tracking your milk, eggs, and bread purchases you don't need crypto to do it at all. Just use a crypto with good privacy to load up your grocery store card (so no one including the grocery store can find out about your other finances) and you are good to go.
