How straining wine for its sediment is a concern of making a tent. More, the range of opinions in the dispute about that wine is fodder for concern (on the daf) about how disparate they are (recall the Jerusalem of Gold ornament). Also: A promise, as it were, that the Torah will be forgotten by Israel (the people) in the future, with a prooftext from a verse in Amos. Which is, or course, of great concern. The daf tries to suss out what "word of God" will be forgotten, and the focus of that concern shifts to the details of the laws of ritual purity/impurity. And then, interestingly, Rabbi Shimon bar Yochai, never known to be a moderate, seems more confident that Torah won't be forgotten after all. Does this discussion itself protect against that Torah being forgotten? It certainly reflects their fear.
