I can personally clearly see the difference between 1080p and 4K even on phone screens. I guess it can be puzzling indeed if 4K seems like an irrelevant buzzword, but for many it's a significant improvement. What's more, I've seen this same argument against 1080p as well. A good chunk of people were arguing that 720p is all anyone would ever need and that 1080p is just a wasteful buzzword.

You keep coming back to needing something. It's a weak argument, because you don't really need anything besides water and a slice of bread. In addition, let's say I do actually need my 4K video conferencing. I would still be held back by the low speeds in question.
As for choosing relevant examples, 4K video conferencing is just fine. You're free to choose another example for your own campaign, but be warned that there will be plenty of people who will claim your example is irrelevant and a waste of resources. Because again, if we're not talking about water then it's a luxury and not everyone will be interested.
