If the IRS was literally going to confiscate his whole salary and property he might have a different view. I expect you might as well.

1. Income taxes != capital asset confiscation, especially as taxes are not anywhere near 100%. The closest thing we have to that is civil asset forfeiture, perpetrated at the state and local levels. Note that civil asset forfeiture is increasingly being challenged by the courts as Unconstitutional.[1]

2. Do you know what happens when you DON'T pay your taxes? The government exercises its monopoly on violence and throws you in jail. If this tax analogy is the best your mind could conjure up to prove "communism is non-violent", your thought process is just as much of an unsurprising failure as every other Communist implementor to come before you.
