It’s an exceedingly poor example. First, value is subjective. It matters not 
what other people may consider, only those who act. Given that people trade 
them (ICO tokens), they have value to those people. Second, the scenario would 
not function given that the value, as with money, is based on the ability to 
trade perpetually.

I said that I would make no further comment given the belief that no new ideas 
were surfacing. However, after giving it some more thought on my own, I believe 
I have found the one case in which a person could value such encumbered coins.

In the case of tracking an asset that becomes worthless at a specific time, one 
could value a record of ownership, and the ability to trade ownership of the 
asset during the period. Consider colored coin type tracking of a theater 
ticket for a specific show, where the ticket is worthless by the end of the 
show.

Now consider the value attributable to renting coin (e.g. to the tick issuer) 
in order to track the ticket. First, there is no net value in renting coin to 
pay confirmation (mining) fees on transfers. The cost of a fee is driven by 
competition and remains the same whether the coin used for payment is 
encumbered or not. In other words, even with value in tracking there is no 
*cost advantage* to renting of such coins for use as money.

But tracking an asset in this manner has required not only a fee for each 
trade, but also the burning of coin. By allowing the lender to recover the coin 
when the asset expires, this part of the cost of on-chain tracking can be 
time-shared (rented), and without depreciation of the coin.

In this case the lender is achieving both a time-locked hoard/speculation and a 
pre-paid rental return. The return to the lender would be the rental price 
minus the opportunity cost of not investing (ie, in production) this coin 
otherwise during that period. This is of course based on the economic principle 
that both hoarding and speculation are expected to produce no predictable 
return. As such the cost of the rental would be driven (by competition) toward 
the cost of capital (e.g. annualized 10% of the coin price) for the same 
period. 

Depending on the term, rental will be cheaper than the outright cost of burning 
the same minimum amount of coin (i.e. dust+1, assuming policy compliance) as 
required for tracking. As soon as the rental cost exceeds the minimum tracking 
burn, rental becomes more expensive than just purchasing the coin. So, for 
example, at 10% market return on capital (rental cost), purchasing the coin is 
cheaper than rental at any tracking term beyond 7.2 years.

As discussed previously, there can be no monetary value of such encumbered 
coins. And as shown above, the non-monetary (tracking) scenario is limited to 
fixed-term tracking. This use of Bitcoin would of course reduce the average 
cost of non-monetary blockchain storage. I’m not sure that is a use people want 
to facilitate with a protocol change, but that’s for the community to decide.

Best,
Eric
