The plan was to give away PAL for 2 years and some people hold it instead of it throwing it away for like $0.0001 each. Capping miners doesn't make accumulating PAL any more difficult. There's only a certain number of PAL being minted per year and it doesn't matter if 1 miner is running or 10,000 miners are running, the same amount of PAL gets printed and split amongst the miners. If anything, this just made it easier to accumulate PAL through mining, but that's not required either. 30% of inflation goes to just staking and holding PAL. The point was never to make anyone buy PAL, but we can't go back in time and make people not dump for 2 years.
