2. Someone can also force you to give them your mail in ballot. How is this different?

2. It's not, aside from that it is more easily automated. "Helping" certain voters fill out their mail-in ballots is already an easy way to manipulate an election.
No. That is one of the most fundamental features of our system. In the secrecy of the voting booth, you can make your voice heard with no consequences to you.
I think it has been recommended before, if you want to see this, sign up to be a poll observer. You will get to see the whole process.
Thousands of issues of voter fraud, and these are only the instances where they got caught. Polling officials are usually the ones that are responsible for mass voter manipulation, just look at what happened in Iowa and Georgia.
Poll watchers are appointed by political parties. It is not something anyone can sign up for and get to do. Monitors also do not directly prevent electoral fraud.
Looks like you've found the problem. Of course you don't get the benefits of a public election if the election isn't public.
