if you live in one on a quarter acre lot you're larping.
Move to the country, spend your money on land and slap a single wide on it. At this point tiny houses are just like mcmansions: conspicuous consumption and signalling.
I didn't watch the video, but there's a lot of "if you don't like it, don't buy it" going on here. If somebody was using government money to subsidize the cost of these or whatever, I'd be opposed. Build an apartment building instead.
But if there's a market of people who want to buy these, knock yourselves out.
That's a shed, not a house. The next time someone over the Internet criticizes me for living in a flat and calls it a "pod" or a "box" I'm going to picture them living in one of those lol.
Also, of all places, I thought Texas wouldn't have had a problem finding a place to build houses. Biggest state in the continental USA and little land suitable for agriculture, I'd expect everyone to own a mansion.
