Even if I lose all of my property, I can rely on the welfare state to provide for my needs so I will not have a valid reason to steal from you.
That's like saying "I don't have to steal from you, I can just ask someone else to do it for me and then receive the stolen property". That's called aiding and abetting.
It is not like that and it is definitely not aiding and abetting
It most certainly is like that. I'll agree it is not aiding and abetting if you would knowingly shelter a tax evader.
It isn't like that. If you want to call it stealing then I would be stealing from the whole of society not
you specifically. I suppose you also think that I am stealing now because I am benefiting from a public education, I have a subsidised bus pass and I go to an NHS dentist.
If I knew someone who was evading tax I would not turn them in to the police just as I don't turn in someone I know who is claiming benefits while working - however immoral I find that.
