Indeed, I wouldn't be shocked if the existing micro-USB standard for charging mobile devices in the EU is replaced/supplanted with USB 3.1 Type-C. It'd make a lot of sense, all round.
What are you talking about? The iPhone uses standard USB chargers, and the only non-standard part (a USB-to-lightning cable) can be purchased from third party manufacturers for less than $10.
Yes you can find micro-USB cables for less than $2, but I don't mind because the utility of the connector outweighs the small price premium. What do Dell chargers do to deserve a premium price?
