What are you going to do with the up to 1 trillion $ that you get from selling your RLCs? Will you always keep all that money in reserves or are you going to do fractional banking just like traditional banks? If you will keep that money in reserves, you risk having it stolen, embezzled, or just having need to use it because your company is running out of money. If you don't plan to keep all of it in reserves, then you are no better than the current banking system + paypal.

In a sense, you are just printing your own currency backed by USD. Just like the US printed dollar backed by gold. And maybe one day, you will remove that backing. I hope you are prepared for the legal mess you are getting into.
