> Although the expected value is still minuscule, it's an unquantifiable improvement (since we can't divide by zero).
This isn't how it works, because the expected value, in monetary terms, is negative once you factor in the cost of the tickets. Statistically, it is a quantifiable unimprovement.
That said, lots of activities have negative expected monetary value, like going to the movies, or going bowling. And it is theoretically possible that you will find an envelope in the bowling alley parking lot containing a million dollars, but let's not pretend that both bowling and playing the lottery are anything other than entertainment products at the end of the day.
