Earlier quoted context omitted.
Imagine you build an AirBnb like solution limited to Switzerland market. AirBnb will eventually come and eat your lunch. In today's globalized world - if you are not one of the bigger players and do not have moat (govt contract, some other kind of exclusivity) - other bigger players will come after you.
You say that, but there are cases even in small countries where this didn't happen. Like trademe in New Zealand which was just like ebay. Ebay still hasn't become the major place to do auctions in new zealand.
Basically no one is competing in NZ because no one cares about the NZ market. It's simply not large enough. Until it is.
I do think there is a lot to be said about not trying to build these giant world-eating companies that require you selling your soul to the devil. Companies like Craigslist I have a ton of respect for. A lifestyle company should be the dream of most, not the crazy disconnected-from-reality VC world we're seeing today.
I simply think anyone betting on their market being small enough to fly under the radar is making a very tenuous bargain.
