This. They think scarcity alone will bring value (price appreciation) if it is done decentralized.
Think of it this way. Rather than that weird parcel analogy alexGR is using, 1mb blocks are like the traditional taxi system. Prices are regulated and supply is limited by a restrictive and expensive badge system. When you're wanting to get home and it's a big night out like new years eve, you can't get a taxi because everyone else wants one. A sane, free market system would bring more taxis out but you can't because the supply is limited and there is no way to adjust the supply.
Removing the block size limit is like Uber.
The "problem" here is we have 53-58% more taxis available than actual demand (1mb blocks vs 620-650kb avg use)
1-block inclusion for every single transaction that isn't mid-to-high priority is the only way this could work out.
There is no way that a spammer can activate a bot, generate 100mb of txs in a few minutes and then expect to be served in 1 block, whether that block is 1, 2, or 20mbyte. If you have a situation like that, with spikes, it doesn't prove that you need ...bigger blocks. The fees will take care of how txs will even out and get processed.
