I find minimalism is actually pretty wasteful in practice. People buy single use, small quantity items frequency, and continually toss and rebuy later if they need that thing. They don't buy extra, and only what they use, but they do discard things rather than storing them.
A great example is a the minimalist traveller -- the one who waits to buy the extra Tshirts and underpants suited for their trip, after arriving, then tosses it before coming home.
Another person I know has a minimal kitchen, but goes out to eat a lot because they can't make more than very basic foods at home with the equipment that they have. Pizza tastes better with a pizza stone, never preserve foods or buy in bulk, have minimal spices, etc.
A third person keeps no materials for making basic repairs around home. Every time they need to hire someone or go out to buy a new tube of glue or a fasteners or WD-40, and they buy the tiny sizes because they just toss.
I've never heard of a minimalist traveler purchasing and tossing clothing but if you've run across some of them I do believe you. Some of the RV'ers on this forum have this approach. The person with the minimalist kitchen might not have to go out to eat much if he or she were satisfied with simple or basic foods. There are people who are.
I have met a few travellers, all male but maybe that is just because I know more male solo travelers. They pride themselves in "no luggage". Typically the ones with a "carry on" about the size of a camera bag, smaller 20L backpack, and no other baggage. Take one change of clothing, comb, but don't even take a toothbrush or paste. Buy swim trunks if they need them, or a pair of shoes if they need more than the loafers they are wearing... these items do not return.
I travelled France for a month this year with a single 40L backpack. My friend pointed out how much luggage that was compared to him. He has a lot of money, which is how I discovered the hidden side of "minimal" travelling. Yes, I could have travelled without a clothes line and laundry soap, but the cost goes up to do laundry. Yes, I could have left my travel cutlery and bowl at home, but food costs go up...
Take a look at minimalist lifestyles, yes, there are Jacob at ERE that actually simplify their lives for a long haul. BUT, some of those shown on TV for decorating and decluttering, for example, actually buy new items and take care of them, repeating 3-5 years....
Technically, "Minimal" clothing does not actually mean that you BUY less clothing per year, it only means that you STORE less clothing at one time...
