Typical handwaving. You make it sound like everything has fine, but there have been many many occurrences of full blocks and delayed transactions over the last year.
My last fees were .00013 and .00005 respectively. If I was just reading headlines and not actually using bitcoin, I would think there was a problem too.
If you are worried about the network scaling, there are criticisms to be had. The network works very well for me, I don't consider that handwaving. I consider Blockstream to be delusional people, it has nothing to do with the network, it works really well if you've tried to use it, even during one of those "stress tests".
As long as it's just a few hackers playing with their toy, yes, it works fine. It fails horribly at any sort of non-toy use case. It couldn't even support the transaction volume of a small city, much less an entire country, or the whole world.
