I wasn't arguing against the reduction in the block-reward, but rather against the harsh and sudden 4-year schedule instead of a smooth per-block micro reduction that would achieve the same thing, without harming price stability - a desirably quality of good money.
Well the fact that Satoshi base the supply to how the gold is mined state it. Satoshi wanted to established an ever inclining currency I guess. Probably with the four year period, Satoshi wants a seasonal spike in price so that holders will get rewarded handsomely and there is a window for the new comer when price spiked and dumped.
