Only if going round in orbit for years is considered without resupply missions.
What's the longest manned mission without a resupply mission? 3 months?
IMHO, part of what CATS realistically means is to lengthen the time between expensive resupply missions because it doesn't seem like anyone knows how to effectively reduce the cost of ANY orbital resupply launch.
Where is money better spent: On developing cheap launch systems for resupply missions or on developing expensive orbital systems that need relatively few resupply missions?
Just asking: IMHO, MHO probably needs some tinkering.
Tinker away...
