In fact you can just go on the waybackmachine and look at craigslist listing from 10+ years ago and see there were short term rentals happening. I suppose those were technically illegal.
Maybe it was just a matter of amount. Before AirBnB there were less of them or less people using them?
Coronado CA also has a 30day minimum.
