Fascinating! I’m in the middle of writing a book on the emergence and spread of the seven-day week.

Two notes:

1. Despite what can be found on the internet and indeed repeated by some scholars, the Babylonians had no awareness of the seven-day week. And they certainly didn’t have a special day dedicated to the sun every seven days. Such a day did exist in world history, including the cult of Sol Invictus (which seems to have influenced some Christian associations with Sunday) and Manicheanism, but these emerged centuries after their host societies adopted the seven-day week via direct or indirect contact with (Jewish) sabbath observers.

2. A great irony is that it’s extremely likely that the association of the planets with the days of the week comes from Second temple Jews. Which is why it’s all over Chazal. See especially Solomon Gandz’s classic article, which is still the best treatment: https://www.jstor.org/stable/pdf/3622199.pdf. In my book, I will (please God) be significantly expanding on this argument. It’s impossible to say definitively that the planetary-astrological scheme was invented by Judeans (seeking to associate the sabbath cycle with high-prestige ideas from Hellenistic Egyptian world of the 2nd century BCE) but its very likely. (Birkat Hachammah is key to this— the only case of the use of planetary names for the week in Halacha). Accordingly, it’s a delicious irony that the Jewish role in the invention of the week itself and of the astrological week in particular are so forgotten by the time of the Meiri (abd then by Art Scroll, which could and should know better) to enable these takes.

OK, can't resist one more comment (did I say this was *fascinating*?):

It turns out that Shmuel's lifetime may have been a particularly important one in the history of the seven-day week, and Sunday in particular, in the Sasanian empire. And given that, it makes sense that there would then be particular concern about commercial dealings between Jews and Christians (and maybe Jews and non-Jews generally) on Sunday. I say this for two reasons:

First, the Sasanian empire (and its Persian predecessors) never adopted the seven-day week. Nonetheless, it clearly developed organically during the first centuries of the commo era under Jewish &/or Christian influence. This is indicated by the fact that the Persian names for the days of the week are clearly based on the Aramaic names (which do not differ between Jewish Aramaic and Syriac). Saturday is "Shamba"; Sunday is "Yek-shamba" (one day after Saturday); Monday is "Du-Shamba" (two days after Saturday) etc. (These also become the names for the days of the week in Turkic languages of central Asia.)

Second, a new religion emerged in this region during the middle-late 3rd century, one that was clearly influenced by Christianity (and thus by Judaism) as well as Zoroastrianism (and so addressing wider Persian society), and it built the planetary week into it, with the Day of the Sun and the Day of the Moon as important (fasting) days. I'm referring to Manichaeanism. (Note also that if Sunday and Monday were fast days [but not rest days], it would have followed that there would have been more commercial traffic on Sundays. Markets and Christian Sunday are also generally compatible at most times in Christian history, which the Gemara seems to know too.

The upshot is that Shmuel may be reacting to the rising secular use of the week, and Sunday in particular, by non-Jews and worried about Jews being pulled into those interactions. This would also align with various statements in chazal that reflect concerns that Jews should not observe the week as non-Jews have begun to do. (My hunch is that this is where לא ישכנו בו ערלים comes from; it reasonably would have taken awhile for us to get comfortable with the idea that non-Jews could observe the week, including religious days on the week-end, without it threatening Shabbat)
