Wouldn't this be something similar to saying hey I want to launch a new app on the Apple App store. Since Apple already has stock, I'm going to issue ownership of this new app to all of the people who own Apple stock (assume this is technically possible).
As a developer I have no incentive to launch this unless I own a lot of Apple stock. Launching an alt-coin where you can claim more of the coins than the distribution of bitcoin is a huge advantage especially if you build something that is worth a lot and not a scam.
