這句句字的問題

I think the sentence should be:
"he has too many things at his disposal to go home early".

The word that contains the negative meaning is "too".
If he does not have too many things at his disposal, he can go home early.
However, since he has too many things at his disposal, he can't go home early.

This usage is similar to the statement "it is too good to be true".
Other examples:
He is too busy to answer the telphone, so he let it ring.
She is too smart to fall for the scam.
These shoes are too small for his big feet.
