RE: You don't need to have

No the previous poster was correct.  A "superconductor" is not 100% efficient conductor.  There is loss of efficiency (waste heat) generated by a superconducting material.  Depending on several factors in the manufacturing process of said conductor and the physical properties of a superconducting matrix, the loss to heat may be as much as 1/1000th of a percent and the material still allow the flow of electrons without electromagnetic interference.  

What you are refering to is an operable superconductor.  These superconductors operate with a very very small margin of loss but they are not an ideal superconductor.  Ideal superconductors do not exist for the same reason that reducing the temperature to absolute zero (Ideal Zero) or building an Idealy rigid structure is not possible under our current technology or understanding of the way the universe behaves. 

In the latter case the Ideal rigid structure cannot be created as it would violate ideal speed of light.  Given an Ideally rigid structure 299277kilometers in length (one light second):  Put a laser and a photocell on either end of same.   Place the structure in an Ideal vacuum.  Place a strain guage or other device for detecting vibrations in a structure at the photocell end of the structure. Simultaneously fire the laser in a one pico-second burst and tap the Ideally rigid structure with a hammer at the same end as the laser.  The result will be that either the strain guage needle moves at the exact same instant as the photocell registers the laser burst or the strain guage registers ahead of the photocell.  In either case you just violated current known limit on speed of light in an Ideal vacuum AND Causality.  Event happened before the Cause.

In the former case you cannot achieve Absolute Zero for any given material (under current understandings of the way our unvierse behaves) due to Heisenberg and his uncertainty principle. Remove all of the heat from a particle so that it does in fact meet the rerquirments for absolute zero.  Now two things are known about that particle that Heisenberg says may not be known about the same particle.  Its velocity (speed along a given vector) is zero.  Also we may derive its current position very accurately.  Heisenberg came to the conclusion that at a quantumn level it was impossible to know both values Δx and Δp for any given particle based on the Fourier Transform for that particle. 

[X,P] = XP - PX = iħ

Heisenberg postulates that it is not possible to know both about a given particle in a given system to a high degree of certainty.  If he is correct then Ideal zero is forbidden to the observer. 

What an operable superconductor actualy does is reduce the resistance of the flow of electrons through the medium to "nearly" zero.  Basically it ligns up the atoms in the material lattice in such a fashion that no matter which vector through the medium the electro travels, the path the electron takes it is not absorbed/retransmitted or reflected by the material.  Another way of saying this is that the Index of Absorption of the material is very close to unity and the Index of Refraction is very close to zero
