That's a good start to having "your own" network, and then you can choose to have packets traverse your network or the peering networks. You could shift egress points around, based on cost and other factors as well. Each link you add can multiply your routing options.

Get large enough, and you can start carrying other traffic too, and eventually start buying/laying fiber. But you know this, it's probably part of your business plan.
