Well, since I'm a big fan of the idea when there's a problem facing the group that one puts the problem in the group's hands to solve...I'd say pose that entire challenge, including what' you've articulated here into a truth telling message. And then ask, how do we want to solve this?
You'll need to get their attention and it may have to be provocative in some way to do so.
You might contextualize it in this way. "I'm appreciative of everyone's needs and concerns on a personal basis, however, what happens to a football team when it splinters into individual agendas with each player seeking to get their own needs met over the need of the team to succeed in a highly competitive environment? Has anyone in the room ever seen that be successful?"
Then follow it up with a challenge..."I"m challenging us to have more than our own myopic vision, and personal attachments to the way things were, and realize that the world has changed dramatically. So much so that without unity of purpose, without a 'Super Bowl' for us to play for that is larger than our individual selves, we will disintegrate into factions that are concerned only with our own version of personal passing stats, tackles and receptions. This approach can only ultimately have us lose market share, market value and whatever additional consequences those losses may mean. So while we're desperately attempting to protect our own patch of turf, the entire landscape gets lost
Bottom line, our company is one gigantic team, if the larger team loses, then each individual in the team loses.
