It is cerebral to suggest that by limiting your ISP to an exclusive few (whilst not increasing rates, clearly), will preserve the utopian IP space the market needs? Who needs growth to re-invest in the network, because once you limit your customer base to a certain number your bandwith requirements will never increase since you have created a static environment, right??? WRONG.
I hope you are not studying in business because comparing IT service companies to restaurants and golf clubs clearly is not what they are teaching in graduate school. Once you stop growth your revenue flatlines yet your costs slowly increase. It is only a matter of time.
