You seem to be comparing honorific usage and common usage. Mister, when used in the honorific is somewhat equivalent to a statement of title, not just a common form of address.
Historically, misterβlike Sir or my lordβwas applied only to those above one's own status in the peerage.
Madam was borrowed from the French, which translates to 'my Lady', which was the past equal to a Lord or a Sir(knight), so is the equivelent form of address to someone of higher 'status'.
Common usage for Mr and Mrs can refer to any 'rank' individuals. Mrs
is a commonly used English honorific used for women, usually for those who are married and who do not instead use another title (or rank)
(emphasis mine).
So Mrs or Miss are merely descriptive, but show no 'rank'. Mr, on the other hand, has dual meaning today; Either as the equal of Madam(showing rank), or as the equal of Mrs.(a term of respect, but not denoting any further 'position').
Notably since it also reflects the womans 'status' as married or not is in modern times considered less desired to some:
In 2009 the European Parliament issued guidance on the use of gender-neutral language which discouraged the use of terms which indicate a woman's marital status.3
