Well The economic discussion probably belongs in a different thread so I'll leave it at that. Oh I went to make a new thread but this guy has made my point better: http://bitcointalk.org/index.php?topic=57.0

knightmb: the number of coins per block is set to go down as time goes on so the number ends up being quite a bit larger than that. Also you have to include the transactions. There have been way less transactions during these first 67k blocks than there will be if millions of people start using the system.

Can someone that works on the code please answer this question of how scaling will be dealt with? The most important thing right now seems to be making a good case for why this system will work to get sellers to adopt it. The pdf is too light on details.
