yoshi,
I am not sure if your argument is necessarily correct in all situations. I would ask a Rav. It is not as simple as you think. I happen to unfortunately have to work on Chol Hamoed as I would be fired if I would not work then. (There are mostly frum employees in the company and there are very good reasons for the company having to stay open on Chol Hamoed and if we would have a choice we would all take off on chol hamoed so they cannot allow that).
There are many situations that one must work on chol hamoed but in some situations it is actually assur. Not just a plus to take off but Assur.
Ask your rav!
