I think it would be really cool if we can stake SFT to a vendors address to pay for a product over time.
For example, if I want to buy a piece of art, the vendor can accept a certain amount of SFT staked as collateral and collect the sfx generated as payment until the debt is paid. Then the SFT is returned to the customer.
This can be something down the roadmap once we have sales volume of course.
People would be able to buy houses, cars etc and not lose their SFT.
