why would cabinets rot i would place drain in an open space with nothing around it

It could work.

" i dont want issues or smells coming from the drain."

You don't want poison sewer gas entering your living space. That's why traps and vents are required on all drains.

so maybe its not a good idea i wish there was a way that i can get dirty water out

Damp mopping doesn’t require a drain. If it does, you are using too much water. A kitchen isn’t waterproofed like a shower. Through caplllary action, water will creep everywhere you do not want it to be, and do damage.
