Poorly-constructed question. I have no problem with a universal charger (the block that plugs into the wall) - the voltage required by nearly all small electronics is consistent and defined by the common chip architectures. By all means, let those blocks use a common connector. This whole thing isn't about the charging block, it's about the cable that runs between the charging block and the device - whether it has USB-C on both ends, or whether it has USB-C on one end and something else on the equipment end.
However, a universal charging connector on the device is a different matter. The key difference is that those ports - Lighting, USB-C, USB mini (USB-A) are also used for data communications. Data port standards evolve over time because data communications requirements change - higher volumes of data tend to demand higher data communications rates, among other things. Locking the world (or even just a portion of it) into a single data communications port with no room for innovation is indeed stifling.
Had the EU had its way several years ago, USB mini would have been the declared standard, and the current capabilities of USB-C would have been unattainable until the EU saw fit to change its standard. Standards-changing would be something the EU would not do swiftly as that would run contrary to their entire stated purpose for standardizing - it would immediately obsolete all those USB mini cables and chargers.
There will be people who say that this will reduce the number of cables people carry around. Maybe they're right, maybe they're wrong. If I have three portable electronic devices to charge at the end of my day, I'm going to want to charge them all at the same time - three charging blocks, three cables. So what's the advantage for me, that I don't have to pay attention to which cable I use with which device? Now, identical charger block/cables can help reduce the need to carry spare cables in the case of possible failure - say one backup with USB-C on both ends, one Lightning to USB-C (or USB-A, considering I like to keep using old, perfectly good charging blocks). Presumably, one spare that fits all is advantageous. But that's hardly a reason to force the world to change, wholesale, to a new standard. If my next iPhone comes with a USB-C, that will obsolete a pile of perfectly functional Lighting cables I already own. How wasteful is that?
