I’m an average woman, at 168 cm height I can easily fit in a cubic metre if I crouch or lay in fetal position.

I often feel like I could accomplish so much more if I had a clone. Just one, more than one clone would become an expense

Anyway if that’s not an option then I’d replicate a variety of:

dollar bills.

Jewellery, gold and precious gems.

Computers, and phones, especially if I can sell some of its parts such as the graphics card

Other luxury items such as parfum, spirits, etc

Eggs

I don’t know, I feel most of these things would lose their value pretty quickly if everyone had a replicator. Kind of like what AI is doing to the creative arts. Only this time it would be the rich getting affected, not struggling artists
