Just take it and do it - this almost never happens. If something is done, then with a great creak.
A certain country has its own standards, and do not care how it is in other countries.
Yes, in the world there are many varieties of sockets and plugs, but in a certain country there is usually 1 standard, and there are no inconveniences. Well, yes, why should we be interested in what sockets and plugs, for example, in Burkina Faso? Tourists have inconveniences if they took some electrical appliances with them, and in that country there are other sockets. Well, for such cases, there are adapters (it's easy to find them or you have to look great - I don't know). Worse, there may be a different voltage in another country. And foreign technology will either not work or burn out. But imagine what it would be like to rebuild the entire electric power industry of the country!
Calibers of cartridges - it's absolutely on my drum: I'm not interested in weapons. It would be better if there were no such cartridges. But I am very interested in railways. Yes, it's inconvenient that there are different tracks, but what can you do? Do you agree to transfer the railways of the former Soviet Union to the world's most widespread gauge track of 1435 mm? And yes, all carts for locomotives and wagons should be changed. If different tracks dock (usually at the border), there are the following options: changing carts (primitive method), simply transferring and reloading (even more primitive method), sliding carts (and this is progress, yes). There are also combined roads or 2 parallel roads of different gauge (this is the best).
And the fact that in some places not the metric system is used (even in a country like the United States) - it's just a habit, but from habit oh how difficult it is refuse! Let it be inconvenient, but so used to it! Switch to the metric system - it should be done. The costs are small, but how much more convenient it would be!

Alexander, have you ever found yourself in such a situation when 20-30 people, for example former classmates, are trying to get together for a meeting? Everyone has their own wishlist, their own affairs, their opinions, in the end you need to eat a pound of salt to organize for all of them. Project this example on countries, but countries are millions of people, different religions, laws, languages ​​... That is why everything is so difficult and long with unification.
