We've never had contents insurance although we will in the future as we will be able to afford it. We do have home insurance though since getting a mortgage. I don't believe it's an absolute necessity as opposed to say travel insurance etc.
Yes we may have around 30k of stuff but in the end as long we have a roof over our heads, food, and each other we could survive without all of it.
It's great if you can afford it but other things have priority.
It's the priceless things that matter in the end (though the little things are nice )
