Obviously Elon also very much wants to launch spacecraft, but maybe has reasons to ignore the launch loop for that purpose.
Elon wants to be able to launch rockets that can land vertically on Mars.
A spacecraft capable version of a launch loop is a wonderful optimization, but doesn't get him to the rocket technology you need to colonize a planet that does not yet have the technology to build such a launch loop. (Plus he has contracts to fulfill that he can't meet in time with a launch loop.)
