The Jews could not attend a Sunday morning meeting because they were at work.
Who said anything about the morning? And BTW, under Roman Rule, Jews, Christian Jews, Christian Gentiles would have had to make their own time to worship, as all of these were not the approved religion of the state; rather, they were tolerated by Rome. We do know early Christians spent a lot of time together worshiping; likely when they were not working; no cottages, no disneyland, Wally world, McDonalds....
More than likely, many would have met daily, and likely communed daily, when able:
Do this, as often as you drink it, in remembrance of me. That sounds frequent to me.
You seem to have a view of history that is more revisionist than historic; until very recently, the work week was not structured as ours is. When most of the world was Aguarian, a 7 day work week was the norm. (I know this because I grew up on a farm), yet there were less distractions from Church, and therefore more opportunities to attend services. Until quite recently, most Churches offered at least two services a week; many offered daily services. Besides, Synagogues that became Christian, kept their customs (which would mean meeting at the usual times), and which is why there was so much discussion regarding differences between Jews and Gentiles in the New Testament, and the validity of their practices; seems diversity of practice is OK, but unity in doctrine is more important (based on my reading of the NT).
Your statement is thin and unfounded.
