Point was not to colonized a place with living creatures. The point was always an advancement of mankind. That was obvious.
You conclusion was not explicit. Therefore a reply with an explicit response to one possible interpretation was posted. Clearly stating whether the objective is to colonize with humans or with machines. Humans colonization on Mars is only desired when one ignores the objective - the advancement of mankind.
BTW, build that igloo deploying 3D printers. On earth, 3D printers are even building bridges. Construction that means other machines can do best science - without humans. Deploying humans to build that igloo is unproductive.
No problem with water. For humans to arrive healthy means that spacecraft may need be surrounded with six feet of water - to protect astronauts from radiation. Plenty of water. But then shortages (for man or machine) is in energy (not water).
