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).
