The only benefit of a decrease in coins over time is it rewards early adopters. With a decrease in emissions over time you are not supporting an increase in users. You are not encouraging the community to grow. You are actually supporting a decrease in users. Why do you think most altcoins do this? After the initial influx of users and the traditional pump and dump, many users leave and very few new users join. A decrease in emissions relates to this trend. If you truly believe monero's user base will increase, you should consider increasing emissions with the increase of the user base.
Reversing the emissions curve could help to even out the market over time if adoption increase. If adoption does not increase, the price could fall with the increase in emissions. I guess the question here is, how much do you believe in the coin and the increase in adoption?
I know you as one who doesn't drink koolaid. You make some interesting points.
As to the bolded, I believe the a big reason most coins use this type of emissions curve is because btc does. As far as benefiting early adopters, that was the point with btc as it was the first of it's kind and an incentive was needed to jump start the process. I guess it is not needed to the same degree for that purpose now for new "real" coins.
But how to change from where we are...............................................................
Yes you are correct about the curve for Bitcoin but it is not quite the same deal when comparing it with an altcoin. If they are worried about being labeled as a 'community premine', they should really fix it. I think i might of used the term emission curve in several places but I think I should of used a different term. I've been sick and my head isnt on right lol but I think you'll get the point. I may make an update in the morning. Im going to bed. Wanted to see MP v2 but now I'm tired of waiting on them to get their shit together.
