It’s like saying most people will never be professional athletes so we should discourage sports.
Or most people live in their home country, so we should discourage young people from taking backpacking trips.
Now I'm not of the view people shouldn't try to change the world but why should that be fixated on a business, why not a community effort, why not research, why not charity based, they all provide you with a range of skills. We have got a saturation of those starting businesses in every industry (especially mine which is quantum computing) and most have a poor idea or a repetitive idea or an idea that so unthought out it can't go anywhere.
(I will say less should go backpacking. Travelling on the whole now has become a distraction from life instead of a discovery. You are better taking that year or 6 months and spending it on something you love to do. That will show you who you are more than visiting some of the poorest nations on earth.)
What I think is important (and why I think entrepreneurship is directionally good) is open-ended exploration and taking initiative to pursue one's own projects. I don't care about the specific direction, but about the idea of proactively trying to shape reality by following one's interests.
I think what you're describing with backpacking is true for most. If the point is to check off a list of Instagram picture spots, then it's more of an exercise in consumerism. If it's to deeply engage with other cultures, languages, and people, that's different.
I guess it's similar with entrepreneurship. If the point is to inhabit the founder personality archetype you see on social media, that's different than to be genuinely solving interesting problems.
