It's probably (hopefully) wasteful in the same way that having multiple browsers, multiple web frameworks, even multiple programming languages is wasteful. Sure, there is duplication of work, redundancy etc. But what you end up with is a much wider surface area to try different things, better things, copy ideas and combine good ideas in different ways. On the contrary, if every country just pools ideas and selects the 'best' via a giant committee selection process, would you really expect that to produce a better result over the longer term? (Genuine question and I'm open to the answer being yes but I personally suspect not).
