What you are saying violates the fundamental design of the Internet. IP
provides a service -- routing packets for you. ISPs provide an instance
of IP access. Everything else is up to you -- you are responsible for
sending and receiving end-to-end packets. "Relying" on an upstream
application protocol gateway is an option, but it must never be
*required*.
Do you similarly rely on your ISP for FTP access, for HTTP access, for
IM access, etc.? Of course not. Where your ISP can provide *added*
value, such as SMTP retries, you have the option of using the ISP.
Otherwise, the ISP is just a bit-pipe, a front-end to the routing
infrastructure of the Internet.
Sorry for the slightly off-topic nature of this post, but since it does
address SMTP's end-to-end nature, especially with respect to SPF, it's
vaguely relevant.

I have to disagree with this statement. The Internet, specifically SMTP
in this case, was never fully intended (nor designed) for direct
end-to-end email delivery. It was designed, again speaking about SMTP,
for reliability and scalability with end users using their upstream
mailserver(s) for communications.
Network routing protocols adhere to this same principal. Just like, you
must rely on your upstream provider's gateway to handle packets, you
should rely on your uptsream provider's email server to deliver your
email.
