Yes, voting is the baseline. It’s the least you can do.
I’m sure that there are anarchists out there who refuse to vote out of principle, but they still do activist work such as participating in mutual aid groups and so on. They’re wrong, but at least they’re still helping society in some way. I think the vast majority of people who don’t vote are just lazy, though.
I consider voting to be the minimum buy-in to ask something of your representative. You may not get that thing, especially if your ask is far outside the mainstream. That’s part of a democracy. The next part of democracy is protecting its status as a liberal democracy, where the people’s freedoms are protected from the government so there is remove for improvement.
