I agree you don't need a tent unless planning to spend time outdoors.
But I don't agree about not taking sensible precautions. I screwed up ( totally my fault ) my first day out of SJPdP and ended up sleeping in emergency shelter at top of Col lepoeder in a 12hr storm. I absolutely needed my emergency blanket *and* sleeping bag. Because I was prepared, I could stick it out safely rather than resort to calling for help.
No need to take a hefty 1st aid kit, but I was very glad of those few grams on that night and all the others when I didn't use it. I would definitely do without a pair of socks or shirt or XYZ in order to take the emergency blanket next time.
Just my 2p.
