The electoral college was created because citizens couldn’t reliably be expected to travel to vote. That time has long since passed, since voting stations are generally (modulo places that are actively shuttering them to disenfranchise people) scattered around enough that it’s not arduous.

Plenty of other countries with rural areas seem to do fine without one. They also usually have much better / more granular representation, instead of a hard cap of 435 for a population that is orders of magnitude larger than at the country’s founding.
