Going back to the Seder, even a poor person supported from the communal kitchen is obligated to drink four cups of wine. But this is obvious since every Jew has to do mitzvot!? - True, but this is only needed because of Rabbi Akiva's teaching that one should make his Shabbat like a weekday, but never depend on other people - even according to his opinion, one should beg, borrow, or be provided.
Actually, Rabbi Akiva gave his son seven instructions, the one above and six more, some of which are "don't live in the city where a Sage is a mayor (because he will be engrossed in study and neglect the city)," "never enter even your own house suddenly, without giving an audible warning" and "engage in business with one who is enjoying good fortune (because his good luck may rub off on you)." The latter, however, is true only for partnership, but not to buy and sell from him - for he will get a better deal.
Later, Rabbi Chanina met with the queen of demons, Agrat bat Machlat, and banned her from appearing to people. She asked for some reprieve, and he gave her Tuesdays and Fridays, but then Abaye banished demons altogether. The Talmud interjects, "But we do see them sometimes!" - and answers that these are stragglers.
