This is true, but BGP offers sufficient knobs to help in situations
where the "naive" algorithms would fail to find the actual best path
(for some definition of "best" - bandwidth, latency, monetary cost, ...).

It gets more problematic when money or politics get in the way of 
"build good networks" - like, two major transit ISPs refusing to peer
with each other, because both assert the other one should buy from
them...  and customers of both suffer.
