This isnt something new anymore and this could definitely happen on Bitcoin transaction where the entire network is really that clogged up.

Lets just accept this scalability issue of Bitcoin yet this had been the main issue ever since.
This has nothing to do with scalability at all. In fact none of the major fee spikes in bitcoin history had anything to do with scalability. They have always happened because of spam attacks. For example the biggest and longest period in which fees went up and stayed up were in 2017 and it was mainly because of the largest spam attack against bitcoin network in its entire history.
Today we are seeing another form of spam attack hence the increased fees.
