I think it's riskier to depend on external technology for child production. Not just at the first level (the "womb" part, the monitors, the process controllers), but at the second level, for the inevitable variety of complex consumables (media, fluids, hormones) which would be required, each of which will require their own supply chains and production processes. Complex dependencies as of today tend not have a unit of production smaller than a factory, not just for assembly lines and such, but also because smaller entities cannot ensure the supply of a team of trained people who can continuously hold on to the knowledge required to keep the process going. I guess it all depends how far down the "tech tree" you're imagining. When you pack down a supply chain in the absolutely most advanced and robust way possible, IMHO it starts to look a lot like the biological wombs, eggs and seeds we already have.
