Asset Names -> Buyer pays attention to Asset Name, Description, Asset Issuer Account and some public opinions
Your idea:
Alias -> Buyer pays attention to Alias (belonging to Nxt account which issues the Asset), Description, Asset Issuer Account and some public opinions
I don't see a big difference. What don't I understand?
The only real difference is whether or not an Alias Name has to be "unique" and whether users are going to get "tricked" or "confused" because they didn't check other things (or their client didn't show it the "right" way).
As I said provided that Asset Name doesn't need to be unique then I don't mind if it remains.
