Huh? You're saying all alts should just do a 100% premine and award their coins to whomever happens to hold bitcoin at a given snapshot in time? And that's more fair than altcoins launching with GPU/CPU mining in a competitive environment where anyone with a computer can be involved? I don't follow you.
There are alts that can't do such a thing for valid reasons. For example, it doesn't make sense to distribute nubits amongst all bitcoin holders just because they hold bitcoin. However, in many cases alts could have used such a wealth distribution. For example, in the case of dogecoin, litecoin, ethereum and namecoin.
I'm also far from convinced that PoS is more secure. Can you imagine the kind of weight Satoshi would throw in if he suddenly started staking BTC after a hiatus (if it functioned like the PoS coins I'm familiar with)? He'd be able to double-spend at will. I've inadvertently gotten 20 consecutive confirmations on an altcoin simply by not staking for a while and then jumping in. A coalition of BTC holders could wreak havoc with PoS.
PoS is much more secure because it's cheaper to buy the majority of mining power than buying the majority of all coins. Can you imagine someone trying to buy more than 50% of all bitcoins right now? The price would just go so high that it wouldn't make any sense to buy them.
How many coins Satoshi supposedly has? A million? It's less than 10%. He wouldn't be able to do anything with less than 10%. Also, I don't support pure PoS such as NXT. Pure PoS is weak but a hybrid such as peercoin is the real good solution. Peercoin started as a PoW coin but over time PoS mining was set to become more profitable than PoW mining. The reason for this is that PoS makes the coin weaker in the very beginning because then it is easier to hoard more than 50% of the coins (as it was with nextcoin). However, after enough coins has been distributed conventionally (using PoW) it becomes safe to switch to PoS mining.
edit:
I now switched my vote back to XT since Gavin admitted that 20 MiB was based on wrong calculations. I support increasing the max block size to 8 MiB as a means to postpone the problem for 4 more years and thus give time for the lightning network and similar solutions to be developed.
