Wouldn't it be simpler if electrical systems take away the neutral and just have live and ground similar to electronic systems?

Ground is localized to a house or installation. Ground is not provided by the electricity companies because that would be unsafe - how could a safe ground be sourced from an electrical generator hundreds of miles away?
How could you detect if current was flowing through some unfortunate person (in the process of being electrocuted) if one of the power feeding wires is actually ground - how could you tell that the current was flowing through that person without a neutral wire? How would you distinguish it from normal load current?
That's the whole purpose of residual current devices (UK name) or ground fault current interrupters (USA name): -
