Michael, 

I meant to say that APN is useful in those "Closed Loop Networks", which are becoming more common for the 5G enabled special services. 

The "end user" or services that need APN are the one who have special contracts with the operators. Not all services.

You've missed the point.
This wasn't about whether 5G was good or bad.
It was about use cases for APN.

(ps: I learnt nothing about 5G from the videos. I actually know a great deal about it.  I don't believe even the moderate claims will come true, for the reasons I wrote about: lack of a trust model between end user and operator.
I think that operators will be seriously disappointed)

Two of the examples you gave me for *APN* (+ 5G) involve the public, using devices they own, accessing high-end sports across a public network.
You've told me that this isn't the use case for APN, so why did I watch these videos?

One example you gave me compared *4G* (3GPP) against 5G for shot-tracking stuff.
Not being a basketball coach, I have really no idea what the effect of latency is on that.  But, again, I don't know how APN fits into this.
