The value of Utility Tokens - CryptoTickets

(this, to all effects, is fiction, not advice).
Today Mr. Positive Blue and Mr. Negative Red meet Mrs. Inquisitive Brown to analyse the value of "utility tokens". Mr Neutral Black has made a through reading of the document and Mr Technological Green is around just in case.
- I have seen many ICOs that sell tokens that will eventually be used to provide a service or buy goods.
- That is right. CryptoTickets, Genesis Vision, WaBi,... and many other.
- My question is, the sales argument for an investor in the ICO is that since those tokens will be used to pay for services if the services are extended and demand grows the value of the token increases. Is that true?
- Well, that is a market law, if you have a limited supply of something and more people want it, you can ask for a higher price.
- Well, I do not agree.
- Why? That is kind of common sense!
- The amount of tokens is fixed, but each one of them can be used many times. The offer of tokens is de-facto infinite because they are not consumed but recirculated. For example, an event organiser or an artist that is paid in tokens will immediately change it for fiat, to pay in the "real world".
- So the only chance for an increase in value is if they decide to hold the tokens?
- I would say that is just speculation.
- Put in even simple terms please.
- Shakira agrees to get paid in tokens 
- That would be difficult to believe.
- Just, accept it for the moment. Shakira sells 1 ticket for 10 TKT tokens. Immediatly goes to the market and gets, let´s say 50 USD to pay the crew, site, etc... So the token has been bought for 50 USD by the client and has returned to the token market for 50 USD.
- That is simplistic, there are many factors to take into account.
- I agree, but basically that is what would happen, and that would add not a penny to the value of the token.
- So, there is no increase in value possible?
- Actually, there is. An event organiser has to own a certain amount of TKT tokens to use the platform.
- Oh, ok, so at the end of all this complex model lies the idea of the event organisers buying the tokens and, at in the end, paying for this new system, at a premium, rather than using the existing platforms.
- That is right in my view.
- And in return they get the value of controlling the sale price of the token, resale and having a system to manage all this.
- I think this is a very risky investment.
- I think there is a good chance for a great reward.
This system actually seems interesting for event organisers, as it allows them to vote and have some control over the middle-man and the development of the sales channel.
In any case, be very careful when you buy a token. Many times you are not buying a "share" of the profit, and, in the worst cases, you may be buying a worthless token or buying for a value that would take years to recover.
