personally just the knowledge of static replication is an asset...... going from the beginning of starting to dynamically neutralize different risks such as delta , vol, gamma, all the way to exposing yourself to only interest rate changes with static replication..
if anything i've learned its that to make money you are taking a view on something.. even market makers are taking views on interest rates, order flow, liquidity etc... you'll never get away from it..
Knowing different structures can give you a better way to express your view on the market.
it is my understanding that most market makers wouldn't take a position in the underlying if they didn't have to.. rolls and boxes are what you want to end up in unless you have a solid view on the risk you have exposure to.. and even then the business of market making is making a spread the cost is mitigate the risk.. The best you can do is find the best risk and TAKE it..
