Customers acting individually have a short-term perspective which leads them to prefer low prices in general, which is why strategies like price dumping work - yet they are illegal for a reason.

The problem is that once the monopolist is entrenched and all competition killed off, those cheap bundles stop being cheap. Hence why you need someone to take the long term view and nip these kinds of things in the bud. A democratically elected government is the best avenue for that.
