I think the value will be exactly 0 or not. Literally 0. I just don't buy the collectors argument for now because Bitcoin is a network. If no one mine because it is not profitable, how could someone even buy the coin? This is why many coin disappeared... So I think that the limited case is very possible... (might take decades?)

This is important for me because if the lower bound of 0 exist, every value >0 would mean that people expect that the value could be greater than 0. I think this is wrong to think that the intrinsic value is separated from the price. But it is also wrong to think that the price reflect something clear about the expected value. If I expect the price could be 1,000,000$, .1% of the time and 0$, 99.9% it seem that if you are not risk averse, a value of 1000$ or less would be an opportunity. However, only the price is available information and not the expectation as different expectation can lead to similar prices.
