As long as you put them to bed properly, no reason to be concerned letting it sit for months.
In fact starting once a month is likely doing damage. That's long enough for the oil to drain off all the internal surfaces. Until oil gets pumped back up to the surfaces, you are getting accelerated wear. I would prefer to keep that to a minimum.
First statement, absolutely.
Second statement, not so much. If starting a (insert any ICE engine powered device or vehicle) effects enough wear to be detrimental to the lifespan of the (insert engine here), then the engines that actually get used regularly or semi regularly would certainly come to an early demise.
OP, if propane, maybe worry about it a couple times a year to prevent any theoretical loss of residual magnetism (which I haven't ever experienced, but understand the theory).
If gasoline powered, it's good to run gas through them, again, every couple months if running on older, ethanol content and/or untreated fuel. If fuel is treated or of sufficient quality, then the benefit is only to keep the magnets excited (theoretically).
Or to simplify it, it never hurts to exercise mechanical or ICE equipment periodically.
