I find CfB self -imposed "ban" from BT forum weird, and of course DaT won't join nxtforum

From
https://bitcointalk.org/index.php?topic=584703.msg6982574#msg6982574You haven't eliminated the fact that there is absolutely no reason not to sign all possible chains in event of a fork.
Can a penalty fix this problem? It seems to me it can.
Bitcoin in it's short history had had ~40M txs. Adding 32 bytes to each transaction would have bloated the blockchain by another 1.2 GB.
So PoW guys were saying that current blockchain size was not an issue but now they want to save 1.2 GiB? It's even funnier that SPV is not mentioned.
One can perform a reorg with no cost by simply acquiring private keys which at one time had (past tense) a majority of the stake.
I wouldn't use the word "simply", unless someone could show 2 cases when ppl sell their old private keys.
There is a chance you will out mine/mint/forge the rest of the network.
Sure, odds r the same as to win 1 million dollars in a lottery.
In NXT when you forge a block which is the best at current height but doesn't enable you to forge the next block (due to incompatible block signature) there is no reason to not use computing power to try and find an alternative which enables you to forge the next one as well.
Could someone show an example? Right now the quoted phrase looks as the beginning of a Sci-Fi novel.
The chance may be low but with no cost it would be foolish to not attempt it.
No cost? Right, 1 (one) SHA256 operation costs nothing, 10
15 * [nothing] is still nothing. Bitcoin network spends no resources, neat.
With no cost, forks will last longer, and reorgs will be deeper.
Penalty makes it very costly to extend multiple forks.
So saying "put a hash of a recent block in the tx and nothing at stake is a strawman" misses the larger context. If there is no cost to attack the network there is no reason to NOT attack the network.
How many times should I repeat that there will be a penalty?
PS: A bonus thought. Nxt consensus rule solves the problem of Bitcoin Fork 2013. Nxt to Bitcoin as Einstein's theory to Newton's theory.
