But in general, the notion creating a new remote capital free of the existing concentrated power structures of the biggest cities is an old idea.
It was the motive behind the build up of Washington DC, which at the time was not very populated and mostly swamp land. The motive was to be free of the unfair influence of any one state. Brasilia copied that idea (it's amazing how visually similar it is in many ways to DC). ...and you might say Constantinople was the original. Similarly, most US state capitols are intentionally NOT their largest city (ie NYC is not the capital of New York State). ...even Vermont chose Montpelier instead of Burlington.
In contrast to Brasilia (which is perhaps the most well-known recent-ish create-a-new-capital-from-scratch initiative), it is far less dense and less occupied. Contrasting to most of the other newer similarly-situated capitals, Naypyidaw is clearly pretty poorly populated and some of its infrastructure is laughably oversized compared to what use it would actually get (Why do you need that road with 10 lanes in each direction? It goes from nowhere to nowhere...).
