The truth is that I cannot agree with what you say. Why is a farm token useless? The farm is your utility, it depends on the farm. Let's take the example of PolyCub and a maximum offer of 7 million. If the farm rewards those who do agriculture with farm tokens, it must have a system that supports the price so that it is interesting to be in the Pool or give more farm tokens. Once the issued token reaches 7 million, the farm must go to the market to buy farm tokens to remunerate the pools, creating a balance or increase in price.
Another thing is that some farms issue a pseudo-free token to them, make a profit and abandon the token.
This has a name that I am not going to say and it could be repeated as many times as you want. In the non-virtual world doing this takes you to a place that I'm not going to say either but that most people would not like to be.
I think I missed the explanation, sorry.
