There's basically a single statement about Denmark and it merely an example that a high tax burden isn't universally harmful. A reasonable counterexample would be a country with a high tax rate that is in terrible conditions caused by it rather than pointing out that Denmark isn't perfect (which is a straw man argument in the first place).

There conflation of paying taxes and "more government" is also on display on in this comment that isn't true. You can have a large poor government or a large well funded government.

I think ultimately the article makes a good point about Canadian's attitude towards taxation and services. Canadian's understand that you get what you pay for. If you want nothing then pay nothing but that means you get poor schools, crumbling roads, and crippling healthcare bills.
