Not correct. Anyone buying at least two T1s @ $600/mo or so each
qualifies for a /24 for multihoming from one of the ISPs and an AS#
from ARIN. Further, anyone with a legacy IP address block (pre-1997)
is also able to announce a block, even with just one T1.

Occasionally (though this is rare) folks with less than a T1 are also
permitted by their ISPs to participate in BGP. I have a quote from a
tunnel provider to do so for $300/mo, tunneling the resulting block to
my two home broadband links.

While most hobbyists aren't going to spend $1200/mo on Internet
connectivity, that's well within the budget of most small offices.

My point is: if we solve the problem for small offices without
disrupting or removing BGP, we'll at least minimally have an
intermediate solution where BGP growth can be constrained by moving
the dividing line between what size network is large enough to
announce into BGP and what has to use the new solution.

IMO, such would be a more modest and attainable goal than trying to
replace BGP outright.
