I strongly disagree on this isolated point. Using the same logic, Bitcoin is vulnerable to an attacker at negligible cost by re-using existing hashing power from mining Namecoin. Any non-scam altcoin is pretty safe using merged mining, since any would-be attacker is going to have it in their interests to invest in the altcoin instead of attacking it. It's only the scam ones that want to pump & dump with no improvements, that are really at risk here. The rational decision for a non-scam altcoin, is to take advantage of merged mining to get as much security as possible. There are also some possible tricks to get the full security of the bitcoin miners even when not all participate in your altcoin (but this area probably needs some studying to get right).
