In the sense that we can currently produce and store some millions of antiprotons at a time, using a proton accelerator "merely" around 200m in diameter. Not in the sense that it would be anywhere near feasible to produce and store even a microgram worth of antimatter.

I agree, but for scale I want to add that a glass of water has like 1000000000000000000 millions of protons in it.
