Are Rx insert goggles worth it for someone who only skis a few days a year?

It depends on how much you struggle with OTG fogging and discomfort. If you only ski 3–5 days per year and your OTG goggles or contact lenses work acceptably, the cost and lead time of Rx insert goggles may not be justified. However, if fogging ruins your ski days or you cannot wear contacts comfortably at altitude, even a few days of improved experience may be worth the investment. Consider it a quality-of-life purchase rather than a performance upgrade.
