A brokerage company operating outside of the US should still be sending you relevant local tax forms. If they are operating in a tax haven, well, maybe don't do business with companies operating in tax havens if you want your US taxes to be easy.
Only during a war, with the demands it places on the public conscience to make sacrifices, would the population acquiesce to an institution so contrary to natural rights and so pernicious to liberty.
There are quite a few countries which do not have global income reporting requirements. Singapore is probably the most notable example.
Some European countries absolve non-domicile residents of the requirement to report global income in exchange for a flat annual fee, like 100,000 EUR.
So it is possible to live a life without being forced to surrender your natural rights like your wealth and your privacy, but it's expensive.
That's hardly surprising. You chose a search term that was very likely going to get hits with anti-tax types.
If you simply searched "pernicious" you would find it being used in many, ideologically diverse, contexts.
Your real problem is with the position espoused (that the income tax is anti-liberty). The use of the term "pernicious" is incidental to that.
EDIT:
The top results I'm getting for "pernicious to liberty" aren't even dominated by tax-related articles:
A tax does not relieve financial stress in any general way. If it did, we would constantly raise taxes.
What a tax does is enforce a collective use of financial resources. The demand for such enforced collectivism increases when a threat emerges that can only be adequately dealt with using such collective action.
A foreign nation, engaged in organized violence, aka war, against a nation, is the most extreme example of a situation where enforcing collective action provides a benefit to the majority, and thus that's when people are most likely to sacrifice their liberty and accept a new tax.
So then don't use those brokerages if you are a USD customer?
