I will focus on one specific type of token which I feel is driving the broader narrative around why new forms of token should be developed- community tokens (i.e., a token which allows different small communities to function better together, and grow)
Tokens are good and bad to community for the same reasons money can be considered as considered good and bad to a community.
Communities grow if net value of the community to its members grows. Money allows communities to scale, as they allow different actors to perform value exchange with less friction - the same reason money is considered to have largely replaced barter in big communities. E.g., I love trying out new experiences, and learning about new subjects or disciplines at my workplace. The head of the corporation that employs me values the service I offer to them, but cannot offer me the variety I demand. So can the corporation not employ individuals like me? Yes it can - by paying me a salary - in fiat money - for my service which allows me to try out new experiences elsewhere - this allows the corporation (a community) to grow.
At the same time, however, money encourages members to be more transactional, and less relational. E.g., If my corporation has a bad year, and suddenly starts paying me less money, I suddenly start distrusting the organisation, and blame for it for all problems. It wasn’t providing me variety, and now it taking away means by why I could buy variety from elsewhere! The corporation therefore suffers from a really high attrition rate, and ultimately stops growing beyond a certain point.
For a community to grow AND sustain, it is therefore important to balance the use of tokens to drive community growth, with the need to develop strong relationship driven communities (which enable value exchanges without use of tokens). Good corporations (and communities) will look beyond relaying monetary benefits - it offers me access to mentors who can help me grow, the opportunity to work on projects that interest me, and develop meaningful relationships with the people I am surrounded by.
