Many places use a combination of both drop boxes and the mail with the latter option being dominant outside cities where your mailbox is across the street and the drop box is much further.

Hurting people's ability to mail their ballot would undoubtedly disenfranchise some voters.

We fight their ability to seize ballots they don't think should be counted in the courts before one ballot gets misdirected and get orders forcing them not to do this. If they do it we fight to get those ballots back in play before the election is considered closed. If they succeed in fixing the election by seizing ballots we refuse to accept the results.
