trademe.co.nz is an ebay clone that got traction in NZ long before ebay ever got going, and now ebay is nowhere there because of the network effect.
Taking a young-ish but proven business model from the USA and rolling it out in your own country can be a very viable way to get success.
However, it takes all the usual combination of drive, talent and capital to do so. And you've got to get straight onto it, because it's such an obvious idea, others will also be doing the same thing.

In 1999, they founded Alando, a German clone of the online auction house Ebay. Only 100 days later, they sold the company to Ebay for about $50 million (€38 million), making them legends early in their careers. Later on, they became involved with Jamba, StudiVZ, Citydeal, Groupon, Facebook, Parship, eDarling, MyVideo, Wimdu, HelloFresh, GlossyBox, Zalando and many other Internet up-and-comers.
While cloning a service in a different geographical area may be profitable and successful on the short term, it's never going to be a Facebook or a Google on a global scale. It's like opening up an Italian restaurant in a small little town that doesn't have an Olive Garden yet.
If that's the kind of business you want to be in that's fine, but it's not the high-growth kind of startup that many of us are trying to build.
It's "just" a cash cow.
This friction also works in reverse, though. As a startup you have a hard time to get the deals with the movie industry, while Netflix already has the connections.
