Your argument is exactly the problem. The fragmentation is what would happen, and the consumers suffer from it rather than benefit from it. This has been proven over and over again by history. When AT&T was broken up, there were like a hundred smaller players, incompatible with each other, and everyone has to pay extra cost to communicate with each other. It is a backward step for the society. The consumers benefit from nothing. Don't just assume more smaller companies means better competition and better for the consumers. It is not necessarily true.
