To my knowledge, they use an integer variable for storing all numerical values. The maximum number for an integer variable is 2,147,483,647.Why don't they just increase the max cash stack? Maybe update it to like 6B or something, idk.
If they were to use an unsigned integer variable instead, they could make a new maximum of 4,294,967,295. However, given the length of time they've used an integer, they most likely don't wish to make an updates as a result of nostalgia. Alternatively, increasing the maximum may create a greater security risk for people who are able to procure duping methods.
I'm sure there are multiple reasons, but to answer your question, they could update it if they wanted to.
