Why do reversible processes do the greatest amount of work?

Reversible processes do the most work, because they have to push against more external pressure

When looking at the reversible, isothermal expansion of an ideal gas, if the external pressure of a system were to be increased even infinitesimally at any stage of the expansion, the piston would move in instead of out. Therefore, the work done during a reversible expansion of a gas is the maximum expansion work possible.

It's also easier to think about the amount of work as synonymous with energy or the amount of effort it would take to do something like that.
