Freedom also means the ability to live without having to suffer overbearing impacts from others. The blockade of Ottawa and the US/Canada border crossings are causing enormous economic impacts on both countries while in the midst of a global pandemic, rising inflation due to supply chain issues. Estimates of the financial impact of this "protest" are not definitive, but are likely in the billions of dollars and are affecting everyone in both countries.
You have the right to protest and make your opinion heard. But at the point that you are actively preventing ~25% of the international trade between two countries while further increasing both inflation and supply chain issues, your "protest" looks more like economic terrorism. Especially when only a small minority of people actually care--let alone support--your position.
To tie this back to the original thread: The author states "There are no other constitutional rights in substance without freedom to transact". But this protest is impacting other people's ability to transact. Therefore, by the same logic the author presents, this "protest" is impacting the freedoms of millions just because a couple of hundred people don't want to get vaccinated or get tested regularly.
The requirement that people crossing the border be vaccinated or have taken quick and painless test to prove that they are not carrying a virus that has claimed more than 5M lives in the past two year is NOT tyranny: it's an minor inconvenience.
