wow your a holy soul to care so deeply about anothers ruchnius! i mean that. i pray i have a wife one day like that. Shachris is important, i find it a bit funny the reasons you listed are all the reasons that apply for a woman also, for men the main reason to doven with a minyan is for saying the Amidah prayer with a minyan, one’s prayers are m’kabal when we doven with a minyan, when dovening alone our prayers are inspected and only if said with proper cavana are they accepted. ofcourse there is no din of minyan by women.
