It might worked with him because he lives in US and there are a lot of bitcoin atms and available services like coinbase . but if he lives in a third world country where no one know what bitcoin is, it would be diffecult to live on bitcoin only even for one week
This should not stop you from approaching these services and merchants and introducing them to Bitcoin. We had the same problem with one of the local pubs... We told them
that we would have regular Bitcoin meetings in their establishments, if they would start to accept Bitcoin as a payment method. They saw the advantage of this and they
asked us to help them. We now support them regularly and we also approach businesses in groups, where we want them to accept Bitcoin. It works VERY well..
