Why This Stuff Costs $2700 Trillion Per Gram - Antimatter at CERN

May be its not the actual antimatter... I am talking about the pair of electron and anti electron(positron) formed by gamma radiations.... I can be a illusive phenomenon mistook by anti stuff... 
One reason behind it is that... Is You can turn electron to a anti electron... Its about the frame of refrence in each particular case.... For example :-a electron moves from left to right... From one frame of refrence... And same phenomena can also Explaned by taking a positron inspite of electron moves from right to left... From other frame of refrence... both means the same...
