In what way is forking the bitcoin blockchain better than starting an alt-coin with bigger blocks?
I think the goals of the fork are probably right on, but I think you’ve made one critical error that dooms the fork, or possibly all of bitcoin. The error is your attached to the existing bitcoin blockchain.
Why do the miners need to make an exclusive choice one way or the other? Why would a merchant be forced to choose which coin to accept (with the consequences of being wrong possibly bankrupting them)?
By creating a fork, instead of an alt-coin you’ve placed yourself in a situation where one side has to win, and one side has to loose. Zero-sum games usually lead to all sorts of bullshit, and exactly the type of bullshit that a distributed currency system was supposed to prevent.
