Oh my. coupling the instability of stateful connections at congestions and all the problem of atomicity/non corrpution of data on the physical layer? It smells like a predictable catastrophe for the future. Not only in terms of a critical path for correctness that is narrower and more sensitive to the noise of the internet, but also in terms of costs. Why do people accept to trade off stability and security for ... what?!

Well. Yes a robot could be juggling efficiently while dancing on a ball. And it would be a nice technical success. And IPSEC/TLS are a ball.

But, why? Can anyone show me a use case where the costs worth the benefits with an actual business explication?

Not just, it is there, so we are gonna use it, lolz. Progress is anything that change, so deal with it we are gonna make a regression and call it progress. :DDDDD

Does every high tech people forgot about money, budget, resources, and contracts?

Bro-tech is tiring.

If you want to synchronize filers for your recovery plan, you don't have to separate them from 1000 km. You can put fiber and use level2 routing with physically protected equipment (level 0 security). You can even if you can stop your activity for 8 hours have your HD backup being delivered by plane in another country.

Ciphering costs money.
