It all hinges the many interpretations of "time". For example, this comment takes 5 minutes from me, during a transition between two larger tasks. The gaming I described though is different. I don't even start a game if I don't have at least an hour or so.

Also, people often mean "energy" or "willpower" by "time". It's like a general, non-material cost of things. "I don't have the time for X" can many times be translated to "I can't imagine managing another context", "I don't want to commit to X", "I can't be assed to start doing X after everything I do in a day", etc. Time in these context is just a convenient scapegoat. This is also addressed by the idea “It’s not about “having” time. It’s about making time.”. For what they really want, people seem to "make time" for, even in the busiest schedules.
