Why can't we link separate Dropbox accounts, unless one of them is a Dropbox team?

Like many my businesses was deeply impacted by Covid, forcing me to lay off all of my staff in my Consultancy company, downsize and focus on my hospitality business that was also deeply impacted. Fortunately I was then picked up as an individual by a much larger consultancy company. This left me needing to downsize my consultancy business teams accounts down to one, but still of course wanting to keep all its valuable data safe, and also keep it separated from my personal dropbox.
I called dropbox support and got advice on how to do this, but after completing it I was totally shocked to discover I was no longer allowed to link my personal and work accounts!
This seems shocking to me that Dropbox would have such a strange and inconvenient rule in place. Surely I can't be the only customer in the world that functions as an independent Sole Consultant that would like to run linked but seperate work and private accounts, and is happy to pay for both???
I have great trouble seeing that there is any technical issue here for Dropbox. ie zero work to make customers happy, and would be more than ok to pay slightly extra for this very basic service. But Dropbox support tells me the only way to do this is to pay for a minimum of three accounts that I simply don't need.

In case someone asks, why not just merge into one account, because I'd like to continue the option of re-expanding my consultancy business when opportunity arises, and prefer to maintain and share the folders with the other associate consultants we have worked with for decades, maintaining known business work flows.
From a dropbox point of view if im happy to pay for two accounts and would like to link them so I can sync both easily... why the hell not!?!

(FYI. This is from a very disappointed longterm customer who has promoted literally hundreds of people to use Dropbox, and is now looking for other storage options)
