This was a very interesting read....
I tend to agree with the few comments about tiny homes being the current "fad", but i can't personally attest to the fact this is driving prices up for used buses, as I'm new to the "ecosystem" myself.
What's funny about bansil's story is that....these people are bashing skoolie.net's community for being "poor" and "hippies"...but they are trying to go the same route...just spending more money...and that makes it "better" or "hip"?
Just out of curiosity, what was the age bracket of these couple?
And to (try to) answer your original question...They've seen it on TV to do it that route, so they might think "that's the way to do it!", without doing more research? Once they saw skoolie.net, my gut feeling is they were put off by the amount of work a similar project actually needs, and steered away from it.
If i had to label that, I'd call their reaction "snob-ish", "childish", "narrow-minded" because:
1. snob-ish: well, that's self explanatory
2. childish: not willing to face a challenge
3. narrow-minded: no possible other ways of doing it; "we'll do it our way" attitude.
Maybe i'm reading too much into this....maybe it's the "poor hippie" in me, trying to finish the bus with leftover ikea pieces...
