Yes, i don't find the protocol particularly attractive.
In any case, while there's a maximum block size, bitcoin can survive on fees. It is unclear if it could survive only on fees without a block limit. But many core devs think so and I find their arguments convincing enough.
But since you're concerned with this, Freicoin will have perpetual reward and is certain that you will not have to worry about this problem you discuss in the other thread.
I have a problem with Freicoin in that
1) Since it is not compounding the 5% surcharge will always have the same mining profit unless the price of the coins increases. An inflationary crypto, mining profit increases if price remains static.
2) the 5% surcharge makes it easier for a miner to accumulate a share of all coins proportional to his share of mining hash in a period of ~30 years.
