The more I think about it, the better I like the idea that emission curve should be linear with a constant block reward.
I actually believe that it would lead to
more general trust on that the coin will retain its value, than the opposite of 100% premine and 0% inflation that is touted as "good and ultimate and the value will only ever go up because there will never be any more token X". Problem is the
number of such tokens is growing at least linearly, and typically the developers abandon them as soon as the initial pump is over. Not formally abandon, but practically.
If a coin is used by a community, either as a store of value or transactional medium (typically and naturally both in varying proportions), it will have value based on the economic potential of the community. If the outsiders believe in the community, the coin may gain speculative value among outsiders. This has been the case with Bitcoin at times, but I would not rule it out happening with Monero soon, due to the special quality of its community. (It may have happened with some other coins some times also.)
If a coin is developed for outsiders, with the developer intent of receiving value out of it, instead of augmenting value to it, it will experience the initial pump and then die. Very bad coins may even fail the pump. (Not all pumps that look high are successful. A successful pump means that there is at least one sucker who buys into it, and that cannot be judged from the price or even the volume alone).
