A "normal consumer", at least in most of the US, can take their iPhone to an Apple store, a Best Buy, and probably several small phone repair services that have small stores or kiosks in a nearby mall or inside a Walmart.

From an environmental point of view it doesn't matter if you do the repair yourself or you have it done by someone else.

The added cost and friction will de facto make it less repairable.
