You can’t handle the logistics of a modern civilization without some kind of administration. Someone has to collect, allocate, and distribute resources to the various public services necessary for a functioning society.

There are “anarcho-capitalists” who might claim to want to dismantle all government in favor of totally unregulated capitalism, but that’s just trading out elected officials for the private boards of massive companies. Else they temper that private power with “citizen advocacy boards” which, after a long enough conversation with an an-cap willing to earnestly answer questions, eventually develop into something indistinguishable from government.

Government is necessary, anarchists want government without oppressive hierarchies. I say oppressive, because organizational hierarchies are really the only way to quickly and efficiently handle large projects. The problem arises with authoritarian hierarchies, when the scope of hierarchical power expands from clerical to tyrannical.
