Why did Rabbis stop shofar for the one in a million person who might carry it?

Concepts: Rosh Hashana 16a, two shofar blowing – standing and sitting, to confuse the satan; Without confusing Satan we certainly lose; Rosh Hashana 29b; Years in history that Shabbos was first day were great or terrible years (destructions of both Batei Mikdash). Meshech Chachmah – we become the sacrifice of Yitzchak. We sacrifice ourselves for the sanctity of Shabbos – of one person in entire nation who might violate. Mishnah calls this day a Yom Tov.

Also story with person who has wife defend him and then other criminal wants his wife to defend him but she was an abused wife -defense cannot work. Shabbos is wife of Hashem. Non-Jews must accept all mitzvos in one shot, Jews can slowly improve. Pandemic taught us that we are not ready to learn all day.
