It doesn't become necessary unless you make it necessary. It makes some places harder or more expensive to get to, but there are plenty of other places to go to.
It's a tradeoff, and obviously if you want to go places where there's no public transport options at all on a regular basis, it's probably a good idea to at least have a license, but for my part that's simply been enough of a reason to bother getting a license.
