Why make somthing that looses value over time when you can make somthing that becomes more valuable over time?
I joined much later than i wish i had, yet i'm ecstatic watching the few coins i got earning me money just by sitting there. I hold no hard feelings towards the people that got in before me, i'm happy for them, but i guess i'm significantly less selfish than your average guy (or at least try to be). I don't get envious of people that have things better than me, i mean, not in the bad sense; i would like to be as lucky, sure, but i wouldn't dare want to rob them of their happiness to have my own, nor do i wish they hadn't been as lucky.
There are no guarantees that bitcoin will hold its present value or even increase over time.
What the op wrote makes a lot of sense. I also think the coins given out for the early adopters were too much too fast, and now its very difficult with only 1/3 of the total coins mined.
There should have been a slower coin distribution and a larger supply of coins, then the growth and value would have been slow and steady, not this huge peaks and valley like we have been seeing. This methodology still benefits early adopters since they will have more coins, but it also allows late miners into the game. Considering the technology is P2P, more miners=more computation power, which is better for the community as a whole.
