when it comes to emission curve, ideally it should go along with adoption.
When adoption is 5 times, also the emission should be 5 times.
What we see now is the lack of capability of absorbing the coins (the price is declining slowly).
Price is the best indicator wether the emission is ideal or not - and it is retarded to maintain something that is not ideal just because it is "holy and unquestionable like the Pope". When they decided the emission rate earlier in the voting, the decision was made on based on the best knowledge of that time - however now we are in September and over 20 % of coins mined, now it is the moment of truth: is the current emission rate ideal for status quo?
Do we have adoption enough to maintain the price (or prefertably even increasing it slowly so that the investors will continue being interested in buying the coins - personally I am not buyer at this moment - I am not dumper neither but I have a stack that I am satisfied and I do not see any reason to increase it especially if there is no incentive for such).
I am dumper if the price starts drastically decline from the current and when I dump, I most likely will never touch the coin anymore.
Ideally the coin should serve all the stakeholders: miners, developers, investors.
The "ever increasing price trend" serves all these stakeholder groups, miners get more money from their mined coins, developers get more donations/their stack grows in value and investors get their annual rate of return.
The blockreward should be dimished or make a stash from each block, for example 25 % of each block rewards goes to the escrowed fund that finances the development and pays after something has achieved according to the burden.
The other way is simply to lengthen the emission curve, it can be done wether making a block to appear every 3 minutes instead of every 1 minute or it can be adjusted by decreasing the block reward for example 33 % the latter will give more time for development and is more gracious towards adoption, it means the later adopters get also relatively long not too expensive coins.
The lowering of blockreward is not bad for later adopters IMO as long as the total coin supply stays constant, it just gives more time for people to join in to the party.
Tail-end aside, the emission curve is what it is. The market has already priced XMR accordingly and it's not going to change.
You have to accept the volatility and occasional pumps/dumps. It's economically impossible for something to only go up and never down.
Two steps forward one step back Fibonacci retrenchment/fortification is the healthiest way to grow with true strength.
A 25% devtax on mining is politically impossible and guaranteed to result in a fork.
The devs will never agree to change Monero as a result of, or in attempt to manipulate, transient market conditions. That's why we love it!
