Wife wants to turn our garage into a 'craft room' - am I crazy for wanting to keep my workbench?

So my wife is on this home organization kick after watching some Netflix show, and she's decided our garage needs to be converted into a craft/hobby space for her. Which, fine, I get it. But I've got my workbench setup where I actually FIX things and work on projects with my 7yo son. She's suggesting I just "move it to the basement" but our basement floods every time it rains heavily.

I'm not trying to be unreasonable here but like... the garage was the one space that was MINE, you know? Am I being selfish? How do other dads handle this?
