These are good points. However, early holders would be rewarded the same, just along a smoother curve, and perhaps rewarded even more, because bitcoin might be perceived as safer to adopt if the price rose more steadily.
And, perhaps more important, actually useful money, and even SOV, benefit users and the economy much more, when they rise in a manner that's stable and dependable.
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.
Well this is why there are 1900+ alt's, fake BTC clones, because then you can put your own flavor of BTC on the world, and tell your user base that the halving is everyday, or every twenty years, but BTC is what it is, and it ain't going to change.
It's always strange to see endless people coming in an telling a community that really has no means of changing anything to 'change'
This is why we have all the silly clones, because somebody thought they could improve the ALGO, but then they find they have no user-base, what's a mother to do? I GUESS you could get on the source committee and convince them to modify the source, however the folks in say CHINA (+51%), may not go along, ...
The subject of modifying the source to implement your suggestion, as you note the odd's of your MOD getting traction, is about 1 in 2**11, one in 2,000, say here only btc-cash, has even came close as a coin, to be being 'as valuable' as the mother herself.
In summary, your suggestion has NO possibility that it will be implemented, and if you go ahead and make a clone-fork, it will certainly be used by nobody,
As to the reasoning of why things are the way they are, the simple answer is 'because'
Given the situation, I suggest you make a clone, and be the only user, and enjoy life, as only you know you got your way
