Help me with English "worth it alone to go"?

Here's link to the article I've read.

--------------------------
The part I need your help is:
The 19-year-old college freshman voted for the first time Nov. 6 and spoke about the milestone with his nearly 67,000 Twitter followers. "Hope y'all go out and vote," the Hudson Jeans model wrote. "Getting the 'I Voted' sticker is worth it alone to go."
--------------------------

Q1) What does "Getting the 'I Voted' sticker is worth it alone to go" mean? does it simply mean "getting the 'I voted' sticker is worth going to vote"??
If it was "Getting the 'I Voted' sticker is worth spending your time as long as three hours in voter line", it would be clear what it means.....(even if it can sound silly,lol)
"worth it alone to go"... what does it mean anyway?

Please offer a bunch of examples~!

This is my first time to know that Americans get 'I voted' sticker for voting, in my country there's no way to prove I voted so we take a picture of ourselves in front of such places as school or public building, where the voting's happening. to prove it.
I hope the rule for the sticker would be passing in my country so near future I get one of my own,lol

Thank you~!

The mere fact of being handed the sticker makes the journey to the voting station worthwhile. The actual act of voting is almost secondary!

The phrase quoted is a very awkward way of stating that - understood by those of a certain social or cultural type (possibly in the USA - recent voting in the USA for president etc), but I am not surprised that it confused you if you are learning English as a second language. Americans say 'waiting in line' but Britons say 'queueing'.

British user of English.

worth it alone to go

The meaning is it is worth to do anything without the assistance of one's former associates
