Not to be all "the market will sort things out", but in general if there is incentive to serve traffic there is at least a lot more potential to fix these things. If you lose potential revenue by congestion, you want to invest in more infrastructure to capture that revenue. Whether that is more base stations for LTE, wifi on public transport or something else. Today that is a cost that you have to recoup from the consumer.

My point was, for very-high demand situations, sometimes tech is just not yet there to support it. And new tech either requires lots of upfront investments (like, replacement of all the existing routers) or doesn't even exist (e.g. that 5G stuff).

I don't know how high the demand is, though. It could be hitting the ceiling, or it could be nowhere near that (and issues could have a different cause).
