Users could gain any crypto-currency by working and being paid in that crypto-currency. Please make it clear that you are referring to a cyrpto-currency which is targeted to investors (speculators) who thus have no way to obtain coins except to buy them in an ICO
The value of currency is denominated entirely by network effect. If only one person owns it, the value is zero. If only two or two hundred people own it, the value is still only slightly above zero. Given the fact that for the value to increase, it requires millions of participants to willingly submit to an extortion scheme, the whole thing becomes a joke.
You are repeating what I already wrote. If the tokens are widely distributed, it doesn't matter if there is ongoing debasement. You are talking about the initial distribution. That is why I said don't conflate unprofitable mining, because that is orthogonal to your point. If you don't understand, you will need to wait for my white paper, because I don't have time to go back and forth with you on this right now.
You didn't define your example well enough for me to comment. When you say "users gain crypto-currency by working", you could mean almost anything, including strange proof of economic activity systems like in NEM
I mean literally doing work that humans normally do and getting paid in tokens instead of fiat.
