Itm option vs future

As title says. I understand the difference between options vs future. But a why not a deep ITM option instead of future?

  • I’m aware of bid-ask spread / liquidity. Is there any other issues with options?

And why would a writer write an deep ITM option when he is better off with ATM or OTM?

By selling deep ITM we can pocket higher premiums

Liquidity is poor when you initiate short. And it gets worse while moves opposite direction. Anyway itm sell is better than futures.
