It's an interesting idea.
I think we should all remember BCNext's vision for NXT and his thoughts regarding fees. I agree with BCNext wanting NXT fees to be low. Imo, 1000 NXT for asset name registration is too high. I think you should be able to register an asset name for 1 NXT. By setting NXT fees high, we are excluding people from NXT because they cannot afford the registration price. NXT should be for everyone.
We should first talk about WHAT we want to accomplish and WHY. I don't want to hear "uh, it's interesting", "yeah, nice idea" or "BCNext said fee must be low".
I want your motivation behind this first. After we discussed that, we could talk about possible realization.
If you cannot pay 1000 NXT for an asset, then what is your asset going to do anyway?
Assets don't have to be physically backed. They can be a form of social credit. Communities that use social credit systems usually do so because they lack capital.
