Dishonest poll. Did New York State have "forced marriage" until 2010?
It did, yes. Not sure what the argument otherwise would be
And having to demonstrate fault in divorce cases is not "forced marriage." Marriage is an agreement people freely enter into; if they later want to get out of it, there is nothing onerous about making them demonstrate a justified reason. You have to do the same to get out of rental leases, sales agreements, mortgages, employment contracts, etc.
Ideally, divorce should be processed as an adversarial civil action with one party having to demonstrate fault or culpability of the other. There are many justified reasons for divorce - adultery, abandonment, felony, abuse, etc. Judges need to hear these reasons and the totality of circumstances surrounding the dissolution of a marriage if they are going to fairly determine alimony, maintenance, property division, child custody, etc.
You can generally get out of a contract if both parties mutually consent to termination, and you certainly don't need to show the state a reason. Why do you think the rules for divorce should be so radically different than the other types of agreement you listed?
