I suspect that's because pretty much every country/civilization in the past 2,000 years at some point or another has banned prostitution as a matter of law/force.

Things changed a bit since Babylon days, about 3,000 years ago.

Even if there were a continuous prostitution enterprise operating over a sufficient timeline (which is not entirely implausible) legal and social acceptance issues would make it unlikely to be a continuous fixed location (brothel) or even a continuous overt business organization.

Is "Enterprise rental" some sort of auto-text substitution error?

Well, it's not what I intended, so probably. Fixed.
