Thanks a lot! I'll make sure not to use 2 out of 2 then!
It really depends on your specific case... There might be situations where such a multisig wallet is the perfect sollution. After all, a "standard" wallet also needs 100% of the wallet owners to agree before signing a transaction
Like the example given on the Bitcoin wiki for instance, where they say "Husband and Wife Savings"... 2-of-2... in that instance both Husband and Wife have to agree to spend the funds on stuff. Also useful for business partnerships to prevent one partner from running off with all the cash.
Of course, if they have a disagreement, then yes, in theory they can block the other partner from getting the funds, but they also won't be able to get them.
I guess where all parties have a vested interest in the funds, ie. they put money into the account... or they "earned" them through whatever business/action, then having an X-of-X account is probably the best idea. Then all parties will want to co-operate to ensure their share is OK.
However, if it is something like a community fund, where people are being given authority over other peoples money... then having it as at least (X-1)-of-X is better... because then it is easy to prevent someone from being a dick and stealing all the money and also trying to prevent the rest of the group from getting the funds if they have a falling out.
Generally, you'd want it to be a majority thing, so 2-of-3, 3-of-4, 3-of-5, 4-of-6 etc... democracy FTW!
