What? Bitcoin account has nothing to do with email address. All you need is a device to generate the private key and there you have it. It doesn't even require an internet access to make one.
You're totally right, but he's obviously referring to mobile wallet clients or some other web based service since most rookies always go for these at the start of their journey. In other words, OP, if you read this, please point out that you are referring to third party clients and wallet services in that specific case. Perhaps it's also good to point out that it's way better if people use wallet clients that generate private keys locally instead of having a third party do it for you.
Let's help him improve where needed.
I like his attempt to at least point out some technical advantages instead of being solely focused on the speculative side.
