Nearly all astronauts are able to walk and do other activities after a short period of resting to allow blood flow and other bodily fluids to normalize with Earth's gravity.
Agree with you, spending billions in rotating spacecraft is to much. Better solution is a simple arrangement to test artificial gravity. Check this file what is your opinion.

The point is that 2-3 year Mars missions are probably quite possible with regular exercise as used on ISS.
Mars/Moon/Space colonisation probably isn't, so spin gravity is a problem we will have to solve, sooner or later.

Never been a colony without babies.
This ain't rocket science. Launching spin-gravity habitats is only limited by mass/launch costs, so the obvious solution ain't rocket science either.

There is no supporting data whatsovever indicating that something that complex is needed. Talk about it once there are data and they show it is needed.
The complexity with spin gravity is minor compared to the whole Mars endeavour anyway, so I find the resistance to the concept puzzling.
It freaks me out that people are seriously planning going to Mars without first doing an artificial Mars gravity long term stay experiment somewhere, somehow.I would have thought this would be at the very least a massive risk to any "Mars Colony Business Plan" if nothing else.
