I'm actually with you on the dynamics thing- the actual oscillations are slower and smaller, but they're cubically harder to deal with. A small oscillation in a full-scale orbital rocket can shred the skin like gossamer. However, the issue is much worse for the general problem of rockets, as the term in the rocket equation[1] is logarithmic. The difficulty takes off so quickly that rockets go from club sport difficulty (eg copenhagen suborbitals) to national research programs when the rocket is just a few times taller. It gets said semi-regularly, but if the earth was just a little bit bigger (again- gravity rises approximately with radius^3) then we would never have visited space.
