There's (somehow) a widely held belief that there is no barriers to entry, on any market, ever. Things from anticompetitive behaviour of incumbents to needing enormous upfront capital invesment simply do not exist. This has to implications:

- Nothing should be done, whether regulation or consumer action, because everything can and will be fixed by the entry of a new company.

- We are living in the best of worlds. Otherwise, a new company would have sprung to fill the gap and then we would be living in the best of worlds again.

I am yet to convince people holding this belief that it may not be the case.
