Why PrEP When Condoms and PEP Would do the Job Better?

I'm still a little puzzled as to why PrEP is considered to be such a great idea, except by the pharmaceutical industry, of course. PrEP is nowhere near effective enough for people to depend on it; they will need to use condoms as well. So why go to such effort and expense? The chances of a condom bursting are very small and if it happens, people can use post-exposure prophylaxis (PEP).

The difference in cost is obvious. PEP would also reduce the likelihood of resistance developing and remove the need for long term adherence. And the side-effects which the pharmaceutical industry don't like to allude to, especially the long term side-effects, will be irrelevant except for the duration of treatment.
