Question

Hello Rabbi. My neighbor passed away, and my brother asked me whether there are any guidelines regarding gathering at a funeral. Right now I don’t know the guidelines, and I’m also not interested in checking. I also don’t usually go to funerals.
But I started discussing it with him in terms of logical arguments, and every second another difficulty and resolution came to mind, so I decided to edit it into a Talmudic discussion. I’m attaching it here. It’s intentionally written in language where you have to understand what is meant. I’d be glad if the Rabbi would tell me whether the line of reasoning is correct or not. (It doesn’t really matter what the Home Front Command guidelines actually are.) If the Rabbi sees this as a waste of his time, I apologize. Thank you for the Rabbi’s extensive activity.
 
Talmud, tractate War
We learned in the Mishnah:
And gatherings are also prohibited…
The Gemara asks:
What is the law regarding a funeral—may people gather?
The Gemara answers:
Rava said: A funeral was included in the general prohibition of gatherings, so why was it singled out? Rather, to teach you that anything that is for a limited occasion is not prohibited.
The Gemara asks:
If so, then say the same about a wedding, which too is for a limited occasion.
Resolution:
How is a wedding different? A man can have a second wife.
Difficulty:
But the same can be said of a funeral, since one has a mother.
Resolution:
There is no difference between mourning for one’s father and mourning for one’s mother except in name alone, as it is said: “Like a man whose mother comforts him.”
Difficulty:
But likewise there is no difference between a first wife and a second wife except in name alone, as Rabbi Shmuel bar Nachman said: Everything has a substitute except for the wife of one’s youth, as it is said: “And can the wife of one’s youth be rejected?”
The Gemara accepts the difficulty and gives a different resolution:
Rather, how is a wedding different? It can be postponed.
The Gemara objects:
What are we dealing with here? A case where he fears someone else may precede him.
The Gemara answers:
That is not difficult, since he can betroth her with two people present.
The Gemara objects:
Then with a funeral too, say that he can bury him with two people present.
The Gemara answers:
Because of the honor of the dead.
The Gemara asks:
And where does the groom’s honor go?
The Gemara answers:
A groom is different, because he is at the beginning of his honor, whereas the dead person is at the end of his honor.
An additional resolution:
A groom is different, because he has the seven days of wedding celebration.
Difficulty on the second resolution:
Then say likewise that a mourner too has the seven days of mourning.
Resolution:
The pain of the funeral is not comparable to the pain of consolation.
Difficulty:
Then say that the joy of marriage is not comparable to the joy of feasting.
Resolution:
It was decreed regarding the dead that they be forgotten from the heart, but it was not decreed regarding the living that they be forgotten from the heart. And from where do we know this? From Jacob, who wept for Rachel only for her proper time, whereas for Joseph he wept for twenty-two years.
