I agree about the TBM's but remember TBMs are one off. I think they may have more reusabilty in space, but still the TBMs you need on the moon are smaller. I think you can create a self-sustaining colony of 100000 on the Moon with TBM's and some seed materials ( oxygen, nitrogen, etc
Once such a colony is built there, then it can be used much more easily to build a colony on Mars.
