The argument for open-ended fundraising sounds a little like idealism to the point of self-sabotage. There is a well known formula for success in crypto, why throw that knowledge away with an idealist gamble? For a project with real innovation, there's no reason to add extra uncertainty to it.
Wanting to increase the number of people that hold coins is good, but it cannot be at the expense of all of them being underwater on their holdings. This will create a widespread negative sentiment, which is far worse than a positive sentiment in a fewer number of people. Having an active and positive community is the lifeblood of a coin's adoption. You kill it right out the gate if the coin is overbought and ends up traded lower than ICO participants bought in. Don't underestimate the marketing value of steady price rises, and alternatively the enthusiasm killer of price crashes.
