My use of “encumbrance” in this thread has been consistently a reference to a covenant. When the covenant can be released at any time it serves no purpose whatsoever, being an encumbrance in name only.
I gave a detailed explanation of opportunity cost, and gave you a scenario where that opportunity cost could actually be used - to purchase a tracking output (i.e., a fixed term asset tracked for that term). And I have discussed at length the use of opportunity cost in the hash-cash-like anti-spam ad scenario.
So it’s not clear to me why you continue to imply that the nature of either covenants or opportunity cost is the point at issue, and by implying I don’t understand them.
**The central issue in your proposal is that constrained coins can neither be used as borrowed money nor the tracking of perpetual assets.** This conclusion is not based on a failure to understand the nature of covenants or the concept of opportunity cost. It is the necessary consequence of attempting to trade something today that will provably disappear tomorrow. The sole possible value of such an instrument is to scam the eventual bag-holders.
A secondary issue, in the valid fixed-term asset tracking scenario, is that the cost of tracking is dust (and at least one transfer fee). The cost of such tracking is a function only of the market price of a satoshi. The financial value of renting one dust output is also limited in time by economic interest (i.e., at 10% it is cheaper to buy than rent if the fixed term exceeds 7.2 years). So while valid, is not likely to be demanded until one satoshi becomes worth the overhead of renting it.
The opportunity of interest represents opportunity cost when forgone. This can be used to show proof-of-cost (ad scenario), and that level can float as a price on the anti-spam market. This is a perfectly valid scenario, as I have said.
The issue with that specific proposal is that it uses covenants in an irrational manner. The ability to release the covenant at any time eliminates the cost it would otherwise represent. One could either simply burn or spend coin outright, or use an actual encumbrance (as you propose) to “burn” (provably destroy) the opportunity, but a non-encumbrance adds nothing except complexity.

Not significant, which is arbitrary, but sufficient - a result of supply and demand. Clearly my intent here is that no covenant on the UTXO is required in the scenario. As the preceding discussions conclude, without disagreement, all that is required is that the (sufficient) output remains unspent, not that it be encumbered.
