40,960,000 coins issued through stake tickets is a lot. My opinion is let the demand determine the supply. But it can reach a return on investment if the inflation rate from mining is kept low. These are just my opinions and everyone is free to have their own.
Cunicula was originally in favour of stemming the initial issuance to a period of 10 years. In the paper, it's described as 27 years to 1%, after which the inflation of the supply because to increase exponentially (but slowly), similar to fiat but slower. This will make mining continually attractive, because it does not rely on fees. Mainly it's designed to to supplement Bitcoin as a goto point inbetween that of equity and actual fiat (in response to criticisms like
these), and indeed, with the decentralized reserve system, intends to have an in place public oracle system to hold fiat within the chain itself.
Time-to-1% inflation (TT1%?) can be tweaked to whatever, so if you guys want a faster distribution, this can be done. Initial issuance must also be tweaked if you want it to stay at a 3%/10y target. It is a delicate issue though; adjusting decreases in inflation so that they occur very rapidly can lead to accusations of a ponzi scheme e.g. protoshares.
