Where do you get "years" from? Why not weeks or months?

Because that would require rotating your crews to and from
cislunar space every few weeks or months. That gets very
expensive, very fast. Expensive even by space-habitat
standards.


But in any event ships, oil platforms, polar research stations,
and space stations all come to mind.

As examples of the "every few weeks/months" model, yes. BOTE,
if launch costs to LEO run $100/kg, an oil-platform style crew
rotation to a cislunar facility would cost roughly $5 million
per man-year. And $100/kg is two orders of magnitude cheaper
than today's costs, well into the regime where SPS starts to
make sense.
