You only need to accelerate to orbital velocity if need to leave the surface in a relative hurry. Think space elevator. You DO need to dissipate the energy you acquired getting there which is why things have those heat shields. unless you can reenter really slow and take a very long time comming down.
The first stage of spacex rockets don't have much heat sheildings, and they don't reach orbital velocity
