You don't 'have' to do anything
Kitasan rolling is solely so you can get a bunch of SRs/Rs + have at least one copy you can slowly uncap over time
She takes nearly max uncaps to be worth using over most other options
Getting one copy will help futureproof you but given you'll be borrowing one for the next eternity anyway, you are more than free to continue saving for other support cards/umas if you're fine going the next 2-3 months with your current deck
