One can, at any time, create a non-interoperable network. Corporations
do it all the time - they create a boundary at their corporate edge and
block transit, entry, and exit of packets.
That is not the Internet. It's a private network based on the IP
protocol stack. Things get muddier if there is limited
interconnection. Then, the Internet would be best defined as the
bounded system of endpoints that can each originate packets to each
other that *will* be delivered with best efforts. It's hard to draw
that boundary, but it exists.
Given this view, I don't think government regulations played a
significant role in the growth of the Internet. We have had lots of
private networks, many larger than the Internet. I know, for example,
that Microsoft built a large x.25 based network in 1985 to provide
non-Internet dialup information services for Windows. It was called
MSN, and was designed to compete with the large private AOL network.
What the Internet had going for it was *scalability* and
*interoperability*. Metcalfe's Law and Reed's Law and other "laws".
Those created connectivity options that scaled faster than private
networks could. Economists calle these "network externalites" or
"increasing returns to scale".
Gov't regulation *could* have killed the Internet's scalability. Easy
ways would be to make interconnection of networks a point of control
that was taxed or monitored (e.g. if trans-border connectivity were
viewed as a point for US Customs do inspect or if CALEA were implemented
at peering points).
But lacking that, AOL and MSN just could not compete with the
scalability of the Internet.
That has nothing to do with competition to supply IP software stacks in
operating systems, or competition among Ethernet hardware vendors.
However, increasing returns to scale is not Destiny. The Internet was
not destined to become the sole network. But all the members of the
Internet (people who can communicate with anyone else on it) would be
nuts to choose a lesser network unless they suffer badly enough to
outweigh the collective benefits.
Individualist hermits don't get this, I guess. If you want to be left
alone, and don't depend on anyone else, there are no returns to scale
for you at any scale. Grow your own bits in the backyard, make your
own computers from sand, invent your own science from scratch. If the
walls are high enough, perhaps you can survive without connectivity.
