BGP didn't start major inroads into the internet until the mid 90s.

RIP can't cope with the scale of the internet today, but to say BGP is essential to interconnecting networks is not right

Huh?

If you take away BGP, there is no Internet!

No other protocol in existence/use today can scale the way BGP has.

IPv4 and v6 run on the honor system too, in that the sender can supply any source address they like.

TCP connection setup is the lowest layer that makes it nontrivial to spoof a sender.

The ability to do this is effectively what enables DNS traffic amplification attacks (and others).

Trust has been broadly effective, but also quite damaging at times. It's part of why I'm glad https is nigh universal - http's trust allowed stuff like Firesheep and all the hotel shit-injection that used to be so prevalent.
