Why are there literally no boards ripped from any of the mainline Mario Party games?

Was looking through all the Mario Party titles on TMR to look for the boards, and none of the main boards from those games are ripped... is there a reasoning for this? How could they be ripped?

I've managed to Rip some of them, they weren't hard to find once I knew what they were labeled. Although they are pretty big and some other split into various pieces. Also the props for the boards are their own separate pieces as well, so like the candy stalls for MP8 or the other props like the cake pieces and Train in 5

They're Labeled with W and another Number for said board, So Koopa's Tycoon Town is W05 while Goomba's booty boardwalk is W02, the same is said for the GameCube Mario party ones as well

maybe this is obvious but for the N64 games the boards aren't models, just a big ol' sprite
