space station module as upper stage on reusable rocket

if space station modules are durable enough they could be launched as the upper stage on a reusable rocket, 

basically a reusable rocket with a separate space station module on top 

this could enable very large space station modules which would give astronauts more living space 

and it would be less claustrophobic environments which would be more comfortable for tourists 

larger space station modules could also benefit industrial efforts in space
