Baltimore has some truly shitty artist warehouse type housing - not surprisingly, a bunch of trust fund kids going to the local art school live there in addition to the stereotypical starving artists. The only way I can sort of explain that is they want to party/put on shows/do a lot of drugs all of the time with no supervision.
My biggest objection to the people discussed in the article is the more fundamental misunderstanding of minimalism (and even really the word "less"). The people in the article ultimately are not addressing minimalism and the question of identifying the essential and eliminating the needless.
For example, on music:
Let's say some dude has 1,000 CDs and a stereo. He says hey, I can consolidate this by getting rid of the stereo, converting my CDs to MP3s, and using my computer instead.
That's not really accepting a minimalist ethic, it's just accepting a transition in how goods are delivered and retained.
In trying to apply a minimalist ethic one would, at a minimum, look at the 1,000 CDs and ask, "how many of these do I need and listen to regularly?" You'd look at your music collection and ask how many of those CDs you actually listen to. The answer isn't 1,000. Let's say it's 25. You would get rid of 975 CDs.
You would do similar if you converted them to MP3s. Say each CD had ten songs, so you have 10,000 MP3s. Maybe you'd hang on to a few more songs you liked, but you wouldn't retain all 10,000 - maybe you'd keep 500.
Likewise, questions about housing, food, etc. would be answered entirely differently than some of these people suggest. They aren't pursuing a minimalist ethic. They're pursuing a selfish ethic, which pushes the burdens of life on to other people.
And ultimately, that's what the whole article describes: it's an ethic that's not really about "less" and more about convenience. It's more convenient to let iTunes sort and store your 1,000 CDs than it is to sort and maintain them yourself; it's more convenient to let someone else cook your food and just pay them for it; it's more convenient to crash on your friends' couches than it is to vacuum and dust your own apartment...
