They don't like to start it with merged mining because then the big miners already set up to merged mine will get most of the coins, but look what DOGE did, no merged mining at first so the existing miners might not all jump on it, then merged mining later once they got their hoard of coins and actually decided the damn thing might be worth securing.
Meanwhile all these scams coming out without merged mining seems to be detracting from merged mined coins, as miners and speculators alike all jump on the latest scams each day instead of settling down to secure the few coins that we might actually be able to make secure by merging them all together.
Some day folks are going to realise that a currency needs to be secure, this storm of scams of the day surely is not going to forever be more profitable than actually securing a few blockchains for the long haul?

Well said. I sincerely hope a secure coin can eventually be more profitable, but as with everything in life, there are those scumbags who will try to make profit exactly as you described. All we can do is continually innovate so crypto is harder to cheat. Coin Magi is a good example of this, with their dynamically adjusted block rewards (doesn't exactly stop deadbeat clones from being made, but it's an excellent innovation against other issues, imo).
