The state as defined by Marxists, is all functioning parts of the apparartus existing to prevent the outbreak of class war

after a proletarian revolution, the proles become the oppressing class, forcing their will upon the minorty (the bourgiouse). In theory, after a series of revolutions engulf the globe, the state becomes unnecessary, and begins to wither away

when the conditions that preclude class war exist, the state is no longer necessary, though this will not happen at once

in the USSR, under the New Economic Policy, the CPSU did have to allow some forms of capitalist industry to exist within their borders

I suppose for a 'small scale' state to re emerge there would need to be some catastrophy, a re-emfocement of compolsary monogamy for women, and a re-consolidation of wealth

the answer you seek lies within the origin of the family, private property and the state https://www.marxists.org/archive/marx/works/download/pdf/origin_family.pdf

the beginning of state and revolution is an easier read and contains some of the same information, transgender warriors touches on some of this as well
