Personally I think the solution is to help and encourage large BTC holders to purchase things produced within the BTC economy. There needs to be a way to facilitate that.
In other words, instead of spending $1000 on mining equipment to see diminishing returns, newcomers can spend $1000 on producing some good and see rising returns.
Oh, no, no, no
What is bitcoin? Why I am being newbie, should trust in it? What motivation for me to sell goods for BTC??!
bitcoin society is some 10 000 people, and current software (with current "constant set") DOES limit bitcoin society in some 100 000 people or less, because difficulty is being normalized to generate constant number of blocks per unit time, 1 bock per 10 minutes.
you see, 10 000 people is NOT a thing to trust in, or to operate with.
and you see, no one miner will remove his mining power from generation process, so difficulty will increase till mining will be unprofitable acording to electricity power costs. This moment will be reached in some 100 000 people attracted for mining, or less.
As 10 000 people, 100 000 people is NOT a thing to trust in, or to operate with. IN TERMS of wold-wide totally distributed currency!
So, your politics is simply turns bitcoin system into small financial 'sect', or 'pyramid'.
I think, bitcoin "constant set" MUST be normalized to reach EXPONENTIAL newbie miner income rate, TILL 1 000 000 people will be attracted for mining. Then you may change EXPONENTIAL rate to some POLINOMINAL one, then to some LINEAR one, and then, to some CONSTANT. This limited constant number of miners should be some 100 000 000 - 1 000 000 000, i.e. each 1/100-1/10 Earth's citizen should be miner or peer.
Otherwise, no motivation for newbies, and apparent bitcoin system failure in nearest future (2012 at 25 BTC per block switch) with max. number of attracted people some 100 000.
