I'm not so sure about #steemit dying if everyone cashes out. I do believe it will make STEEM stronger because it only shows that STEEM is liquid.
If people stayed where they are and never traveled or have gone to holidays because they think it's not adding value to the society, that my friend is a wrong concept of going on holidays.
It may seem self-serving spending holidays and spending hard-earned money just to "enjoy" although some may have that same intention. But even then, going to places, meeting people, learning about culture, or even learning how one travels from his hotel to a restaurant in Bangkok is an education in itself.
I'm sorry to disagree with you, and you have the right to your own opinion. But traveling, even going on holidays, gives us opportunity to get educated no school or university can ever provide.
