The entire point of the WTO was that countries can cooperate globally to reduce tariffs and other trade barriers, so it does matter what you think of other countries' decisions.
I propose an idea that complete lack of protectionism (subsidies, tariffs, quotas) should not be the goal.
If we (countries) all are fully open, then we are fully globalised, and likely overall prices are lowest. (that is good)
But such system is fragile and very “shockable”, it entirely depends on stable shipping numbers and stable inter country agreements, both of which can be easily sabotaged (various motivations and agendas; just in 6 years: covid, Trump, Yemen Houthies)
Not implementable, but fun idea: protectionism based on distance, even within a country. E.g. supermarket must buy 10% of its apples from within 100km, 20% from within 1000km, 40% from within 10000km. (It does have numerous problems, feel free to identify them in comments)
