I'm not sure what your hostility is for. It's a question of relevance to this forum specifically. Thanks for the downvote.
You railing against "Western Society" strikes me as off base, like you have an axe to grind. It doesn't matter to me if he does it once or for the rest of his life. That not why people post stuff like this to hacker.
However what does matter is this video was shared on HACKER NEWS, probably because of its entrepreneurial based content. Most of the links posted here have some sort of connection to either technology, science and/or entrepreneurship. It's not the latest javascript library, but he is using eBay + hustle to brick and mortar stores to generate revenue.
The question is it's relevance to this forum. The guy is trying to make a business, and exploiting gap between supply and demand. That part is interesting. The reason why it's relevant is "can anyone use this video to recreate a similar business?"
Is this video demonstration of a potential service a sustainable, repeatable and potentially scalable business model for others to emulate on this forum? My humble take on it is NO IT IS NOT.

Literally most of the people who come to hacker news. We're not to watch some guy drive 700 miles to 20 Walmarts to buy 100+ monopoly board games. Most of us are interested to see if this can be a real business idea.
Which is why I conceded certain points about the idea. He's working for himself. He's hustling. I don't know if he does this full time or in addition to his regular job. There is something impressive to what he's doing. Making $2500 over the course of a weekend is pretty impressive. And if you could keep making $2500 per weekend doing this kind of thing that would be of interest to me, even if it isn't my thing.
