One could in theory make a switchmode gyrator that would make a

I have an application for that, but it would take too much engineering
and runtime complexity to make it worth doing. I guess I'll just have
to buy a bunch of giant, heavy custom toroids.

I'm sure that there are other reasons why an inductor
will be used besides the lack of time/energy/resources
to 'design them out'.

Energy storage is just one means to an end.
