if it’s brown rice, it doesn’t last years- 3-6 months is good, you can vacbag and freeze, though. But while white rice might last years at room temperature, you’re still paying for storage, and running the risk of vermin or it getting wet or otherwise ruined while it is being stored. This is one of those “you do you” things, but, I know my pantry doesn’t have space for 2 years worth of rice…
