The ability to tokenize, even with NFTs, opens the door to what you are mentioning. Suddenly barter isnt really that since the exchange would be in token form.

For example, a token might entitle me (as the holder) to three hours marketing service (or whatever). That is really where we are embarking upon new territory.

And all those tokens could be paired with HBD.

I'm just writing this down in case I forget, it wouldn't be the first time. lol

I find it happens more as I get older.
