why are all of these people like owners, managers, workers, government, consumers, community important to business activity?

Every person has defined role in an business activity, if one is missing another get affected. Taking from your question if there will be no worker what will owners do ? if there would be no government then who will regulate ? or if there wont be consumer then for whom to make product for ? so every people is special and wanted for his ability.
