Even if that does bring in more people, it doesn't address any actual issues.
Well, you need Steem to have Resource Credits. And when RC delegations are ready, dapps will need Steem to delegate RCs to new users to transact on the chain. With the RC delegations, onboarding becomes easier, because it is no longer a requirement for the user to by Steem. To ease onboarding even further, there's going to be light accounts where the dapp is having the control over the account, but the full ownership of which can be given to the user at will. This is the model that 3Speak is already using.
I don't even know if we can really call the small payment of Steem to create an account an issue at this point. I made a post literally at the same time you started replying, it mentions how we had massive growth here in terms of users, just nothing was done to hold them in. Creating an account was considerably more expensive then than it was now.
