Wouldn't that mean you could only have new transactions when the next magic number comes out?

Currently, all bitcoin transactions have to wait until they get into the next mined block, which is about every 10 minutes (I think?)

But that time serves a purpose for security. So for the proposed solution the time would have to increase from 10 minutes to 10 minutes + how ever much time we want to save hashing energy for.
