Is a back-up bag a silly idea?

While my go-to bag is my LV Pochette Métis, I have been LOVING my Coach Tabby 26 in Dark Stone/Brass.

Y’ALL.

The love is real for this one. I’ve been so stinkin’ happy with this lil bag that I put my PM back in its dust bag (😱) for a little while as I’ve been taking it to work every daily. I’ve never been a Coach girly, but this one has made my heart so happy.

My question is, should I purchase a back-up Tabby 26 in the same color way? I saw it’s completely sold out but gosh I’ll be devastated if something happens to it.

Is this a stupid thing to do? I have brought my collection down to just three bags as I’m trying to keep to a minimalist collection (plus I plan on purchasing one more bag by the end of year to round out my rotation), so should I even think about this? Was going to purchase on EBay or Poshmark if I can find one that’s almost brand new/in good shape.

Thank you for the advice!
