It sounds to me that you are confusing origin of life, and a
description of it. In biology the view is indeed that firstly there
were re-producing beings, and later they became self-producing in the
sence of autopoietic [by meta-transitions if you want]. But I don't see how any
living [autopoietic]
being or system can arise without evolution by re-production. So
there is no tension between selfproduction and selfreplication, in
fact they can't do without each other.
In another post somebody said that there arer living systems that do
not need self-reproduction or self-replication. I would like to know
what he means, because I find that impossible. Unless you stretch
autopoietic to social organizations, in which self-reproduction in
the biological sence is not neccesary.

A good example would be cristalline-growth and the growth of a colony
of bacteria.

I think this is the same as what I just said.
