I know its literally rocket science and a lot of very complex systems need to work together, but shouldnt we be able to iterate on a working formular?

Rockets require an absurd amount of power:

The largest jet engine produces around 100,000 lbs of thrust.

The Raptor engines that SpaceX use produce 600,000 lbs of thrust, and there are ~~9 of them on the falcon and~~ 30+ on starship.

(Edit for the correction there, Falcon uses 9 smaller engines that have around 200,000 lbs thrust each)

The Shuttle solid rocket boosters produce 3,300,000 lbs of thrust each.

Containing that amount of power in a small space where you are trying to make everything as light as possible is very difficult no matter how long you’ve spent working on it.
