1. Why should harming a million people identically reduce their right to a fair legal evaluation and possibly compensation for damages? <-- maybe it makes sense for large corporations to carry insurance to pay for the potentially massive legal costs they could impose on governments? 2. Shouldn't we be able to quickly resolve these cases assuming there are no substantially different pieces of evidence?

It doesn’t. You can almost[1] always opt out of class action lawsuits to pursue your own suit. This would be expensive and unwise for most people, but you have right.
