You sound angry. Might I suggest taking a deep breath? I don't pretend to know everyone's situation. What seems easy for you or me may be next to impossible for someone else. As I pointed out in another comment, mail is not 100% reliable and there can be delays that may result in your ballot not arriving in time to be counted. Using a drop box, on the other hand, ensures that your ballot will reach election officials in time.
And you still haven't answered the question: Why does there need to be a hard limit on the number of ballot drop boxes at the state level? What does that accomplish?
Compared to 2020, access is restricted - at least for counties that employed drop boxes. While it's true that there were no mandatory drop boxes, county election officials were allowed to determine how many they needed. Fulton County had 38 drop boxes in November. They will now be restricted to 8. The drop box that Governor Kemp used in the general election would not be legal, for example. And it affects rural counties too. I can't find the article again, but one election official said that they had five drop boxes in their county (one at each polling place), but they will now be restricted to one under the law.
