I'm not interested in either of the "Satoshi willed it", and "but I want it sooooo bad" non-arguments.
I believe they are not as secure or distributed as Bitcoin main.
Please, explain to me how merged mining is insecure. Take your time.
Bitcoin has never been faced with an extended period of time when its blocks were full. That means we don't know if altcoins will suddenly take market share in the event that blocks start hitting the 1 MB limit on a regular basis. Your argument is therefore, with all due respect, another case of you being disingenuous in this debate.
My argument is perfectly fine, and you actually add to it.
For how could we come up with a sensible solution if we haven't actually experienced the issue?
