That is true, but only if we are the only ones using
private ASNs.
But if happens that some people already uses private
ASN for other
purpose, they would be in trouble connecting to 44net... because there
would be collisions.
I see no point of using public IP addresses and route
them using private
ASNs. It may be that I do not understand BGP well.
It is important to note that the routing in this overlay network,
let's call it BGP44 from now, is running as a separate BGP instance
that is not combined with BGP announcement to internet or private use
of BGP. The BGP44 instance will only distribuite the routing info
for AMPRnet subnets, similar to what is now in the IPIP routing table.
Also, even though there could theoretically be collisions, in practice
there is not much risk because there are 94,967,295 available AS numbers
in the space that we use. That is 8 times more than the number of IP
addresses we have left.

BGP is a signaling protocol which does not carry any traffic, while
BGP44 is suggesting otherwise. Essentially its just a regular BGP
network. If you are doing this the BGP way, you'll still need to use
ASNs, private or public, and use maybe roa to authenticate the source of
the prefix, i.e., someone with 44.1.1.0/24 may fat fingered to
44.21.1.0/24.
It looks like you are making something like dn42[0] but with public IP
space.

Go for broke and establish ARDC as a RIR with IANA. That would allow
for getting real assigned blocks of ASNs from IANA dedicated to amateur
radio and also clear up a lot of the concerns about assignments as 'fair
and equal' assignment policies are a requirement of all RIRs. It would
make ARDC a real life internet registry to benefit all amateur radio
operators worldwide.
