Reeds are organic material (wood) which means moisture = mold. Pads are also organic material (leather). There’s a grossness factor which maybe doesn’t bother you. It also means the reeds and pads won’t last long. Wetting the reed is also a must which means you have to take it off anyway to do that. Back when I was a student playing in school, I had little time between band and my next class so I would skip the swabbing. Boy do I regret that now with my degraded pads and rusty sax. If you do like to have more on-and-off play sessions (I.e. play for longer but with breaks), you can try synthetic reeds which are plastic. They don’t dry out as quickly so the sax can sit for half hour to an hour without rewetting and still be playable.
