What if gold and diamond were abundantly available ? It would lose its value .
Hence its your call , you either want your coins to be just another alt coin worth shit or a really good scrypt coin which has the capacity to be of high value
you are mistaking the absence of a cap for 'abundantly available' ... new gold and diamonds are found every day - and they are still valuable... a coin can have a small new amount to mine forever and it would be ok, as there will be lost coins along the way
