so instead of simply financing military operation and staying home, he went in himself?

in some sense I even respect that decision

Not going probably never even crossed his mind. Social status in Roman society was very strongly influenced by military success. He was a previously successful general.

Historically (with all the accuracy you get when you summarize all of history) raising an army and not leading it was effectively telling everyone that you should be replaced by whoever did lead it.

The point was to win military glory since he resented being outdone in that respect by his fellow triumvirs.
