Thanks for your post. I've always looked at it this way:
Models like arbitrage are a good low-risk way to get your feet wet with selling on Amazon, but it's better for someone who has more modest goals. It's not as easy to make a full-time income with part-time work. It can require a lot of time to source inventory, so you'll end up hitting a point where it's difficult to grow and scale your business.
Of course, there are exceptions to this as I know there are sellers who have been able to create significant full-time businesses using this model, but it seems that most are just continuing to trading time for money like a regular job.
Of course, I'm biased since I'm a private label seller and I know that works for me and others I speak with regularly, but I'd be curious to get your perspective on my comments above since you're just getting started with the model. Is this a concern of yours?
Living overseas, how are you managing the logistics of an arbitrage model?
