The postal office doesn't get to choose which of my letters it's ok to delay or throw away, they should just deliver them. Same with my ISP.

It's interesting you say this in the context of real-time media, because I believe a network can give time guarantees ("any packet I deliver on this will be delivered within x ms") or delivery guarantees ("all packets will eventually be delivered") but it's hard (impossible, maybe) to do both.

eMail is an assured store-and-forward service.  IP packets are not.  Most users are unwilling to pay for guaranteed bandwidth availability to an ISP, who in turn would have to pay for guaranteed bandwidth upstream, and so on.  

Personally, I want my fair share of the shared 'roads' no matter how many others are sharing them, and I expect the 'last mile' personal link to have (at least) the capacity that was sold to me.
