You're assuming people are the same as you - I follow the same but I live out of suitcases and can travel at a moments notice for the best flights and pick up an airbnb somewhere.
But this is the life I want - literally 95% of my things fit in 2 suit cases, a third is my bike and a bike is a bike thought if you want to get really technical you can count the wheels, the brakes, the brake rotors, the frame, chain, groupset, etc as different but together it's a bike (and a bike bag!) but I do count the clothes/water bottles, etc.
It's also so cool because you can use pivot tables to group items into necessary or not - so if you want to wing just a one backpack 25-40l trip, you know what to grab and also the rolling cost of items associated too - and for more fun, deprecation, purchase cost, etc.
I enjoy it, but thats the spirit, a pair of socks = 1 or do you have 12 socks?
