How come ‘concern’ means ‘commercial enterprise'?

No, it’s not a “concern” in the sense of “worries”. It’s a concern in the sense of “commercial enterprise, entity”.

I need much more detail than [these snippety sentences].

PS: From the sense of busyness came the business meaning of “concern” I suppose.

Please trace all shifts from Latin [concernō] (“I mix, sift, or mingle together, as in a sieve”)] to this sense of English ‘concern’? How, and why, did [concernō] shift to ‘concern’ meaning [“an establishment for the transaction of business”]?

1580s, “regard, reference” (a sense now obsolete), from concern (v.).
Meaning “that which relates or pertains to one” is from 1670s.
Meaning “solicitous regard” is from 1690s.
Sense of “an establishment for the transaction of business” is from 1680s. [my emphasis];
colloquial sense of “a cumbersome or complicated material object” is from 1824.
