The core of what makes the SAFE Network what it is, is privacy, security and freedom by default. The overall structure as well as all the pieces work in synergy to accomplish this. What you are describing is nothing like SAFE.
This post is slightly dated, but gives you an idea of the network structure from an encryption/default-security angle. Exact implementation has altered a bit, but the post is still basically accurate. I recommend it regularly.
