By running the badblocks you're wearing your stick down.

I don't remember the particulars, but the technology does have a
specific amount of writes per block.  Yes, flash based storage does have
an underlying "reallocation" technique, as well as an "even" writing
method, ie. tries to write to each block the same number of times the
other blocks have been written to on average.

It all depends, though I cannot specifically tell you that you need a
new stick within the next x number of months, I'd have a backup, in case
you would need to go to it.
