That article (from 1979) indicates that the only legal restriction is that it must be dispensed into an approved container. More recent advice from the API indicates that fire codes usually restrict the storage of more than 25 gallons (~95 L) at home. Many people in rural areas would have orders of magnitude more than that. So it seems that, in the US at least, it's not illegal all over.
