Correct me if I am wrong, wouldn't that mean if the stock value goes down and is sold at a much lower price, the collected tax would be much less?

And isn't it possible to reduce tax even more from capital losses from stocks?

Yes to the second, which is inherently self-consistent policy in a taxation system that taxes income/profits.

The first depends on the type of compensation and whether a prior 83(b) election was made (and taxes paid at that time).

But in general, the money’s going to get taxed and if the taxpayer is a US citizen, the US will get its cut.
