The Bible says Joseph went with Mary. Why is that a problem for you?
It's not a problem for me. Yes, Joseph went with Mary. We can agree on that (you seem to have a difficult time recognizing what aspects of an argument are in agreement and which are in dispute.)
The Bible does not mention anyone else going on this trip. From this, you assume they went alone. I assume the Bible does not mention anyone else because the author may have considered it an unimportant detail.
The Bible does not say one way or another who was all in their travelling party. You argue from this silence.
It's a logical fallacy.

Can you imagine when the last apostle was gone and the wars that took place and how many were killed for processing copies or even original or seal of approval!
I cringe at how many scared manuscripts were destroyed or burn!
