I still don't understand why it cost more to SEND something if you have more transactions going IN to your wallet.
Why does the system care where I got the money from (as long as they are verified)?
if I want to send 1 BTC why does it matter if I accumulated my "wealth" by 5000 or 5 transactions? This hurt business that sell t-shirts over people selling gaming computers then, since they have more transactions with less money coming in.
It only hurts if the amount being spent is so small as to be considered "spam" by the network.
Amount being spent you say, is that spent by the people buying t-shirt or the t-shirt company?
Also you said;
"If you have inputs valued at 0.00000001 BTC (frequently received from SatoshiDice), they'd have to age for 10,000,000 days before they could be individually spent without a fee."
So for example;
I have a few of those 0.00000 transactions is there any hope for me to ever be able to spend bitcoins without having to pay a few? Or are was my first day in bitcoin world with a lot of small transactions messing it up for the rest of my life?
