The problem of single stage to orbit remains. They need to advance rocket technology beyond bell housings.

Moveable thrusters could be an interim solution for the large rockets but for the small rockets something else needs a solution.

Perhaps they could design a thruster that increases capacity with altitude. Sure it would be a bit more complicated than stages...but once it is complete we would have a variable altitude thruster.
