1. We have no practical effective way of "collecting" ozone from computers 
to transport to the stratosphere. Ozone is a highly reactive molecule that, 
when adjacent to another ozone molecule is going to form 3 O2 molecules. 
Therefore by the time we got our collection of ozone molecules transported 
to the stratosphere, they would probably all be O2 molecules and no use to 
fixing the problem.
2. It would cost a lot of money to develop a technology that would 
transport ozone to the stratosphere, and no one has committed the time or 
money to developing that technology.
3.  The ozone depletion is caused by Chlorine molecules that have migrated 
to the stratosphere from the troposphere, and can continue to deplete ozone 
more than once, so to solve the problem it is necessary to get rid of the 
Chlorine molecules (and the sulfur dioxide molecules) that are making the 
reaction possible. Putting more Ozone in the stratosphere doesn't solve the 
problem as long as there are Chlorine molecules there to continue the
