I see what you're saying, but I think it lacks perspective. Yes. the government has a lot of advantages, such as the ones you list. But remember that

a) A criminal jury verdict has to be unanimous. So the "defense's" jurors have to vote to convict along with the "government's." This is clearly designed to benefit the defense.to

b) The "beyond a reasonable doubt" standard of proof. Defendant friendly, to say the least.

c) Jurors are notoriously unpredictable. I don't know of any lawyer (and I know a lot of lawyers), whether a defense attorney or prosecutor, who would tell you that they can reliably predict what any given juror will do. The best you can do is ask questions like "do you think that anyone convicted of a crime is probably guilty" or "would you feel comfortable sending someone to jail" and remove the jurors who give the "wrong" answers to those questions. And note that these would typically be "strikes for cause," and therefore don't count against either side's total number of peremptory strikes.
