With steam your entire construction has to be able to stand up to pressure. This will make it very much more expensive not to mention heavier. I don’t know about where you live but around here any steam engine has to be certified pressure safe. Past history with steam engines has seen far too many accidents due to steam explosions. With hot air you only need to worry about high heat resistance and absence of combustible materials which is also required with steam systems.

Just because it sounds romantic does not make it practical or realistic.
