Sorry, Mark, but no comparison to the Point Pleasant canal. While I'm sure that an experienced, skillful sea kayaker such as yourself could easily negotiate the canal, were no other craft present, if you actually tried it in normal use, some gun-toting powerboater would probably shoot you, in a fit of nautical "road rage". And a local jury would indite you, not him. Believe me, the ban is a triumph of common sense.
I have to say I question the way you look at things?
"gun-toting powerboater would probably shoot you"
Show me where a gun-toting powerboater has shot someone anywhere in the USA and the other person was indited.
Your argument is really pretty Silly and you should rethink your stand, access to a resource is something that once given up is almost never reclaimed. I have been watching these issues in a number of communities for decades and they always go the same way. If you fail to make a stand you will loose access to the resource.
You called this location a "an integral part of the Intracoastal Waterway" to me that sounds like if a person would like to use both bodies of water on the same day without this channel you would have a 1.9 mile portage? why because some wont be able to handle the conditions the channel may have at times? If you ask me that sounds like a poor excuse to limit access to a shared resource. I promise you that that channel is maintained with money from people that dont own power boats.
