This is a pretty bizarre outlook on it. Timegating is there to a) ensure that players retain their monthly sub instead of going into a sub-raid-unsub repeat cycle, and b) ensure that players don't feel compelled to spend 16 hours a day playing just to stay competitive.
Not an easy balance to maintain, for certain.
If you have the rl responsibilities you indicate, I don't believe you'd even hit the currently implied time gates in any significant way.
