This is a very popular industry standard with a well known path for updates – it seems pretty reasonable for the government to simply tell the stragglers to adopt it. Unlike the concrete in your example compatibility is a bigger concern - imagine if you needed special shoes to walk on AppleCrete - and the service lifetime is much shorter so waste is a very reasonable concern.

Lightning has been around quite a while no? So waste wise Apple isn’t doing too bad.

It's definitely not terrible — microUSB was so fragile that people replaced cables a lot more frequently. My point was simply that if you're talking about concrete, the waste is on a completely different timescale — Lightning cables are pretty durable but even a decade is ages in tech while buildings and sidewalks are expected to last an order of magnitude longer without outside damage.
