There is a huge difference between "globalisation" and "globalism"

As you say, the former is inevitable and (arguably) has been going on since humans first began.

"Globalism" on the other hand, is just western imperialism redux.

It is sold to the "fluffies" as a kumbaya world-without-borders where peace will reign forever.

This is unlikely. A world without borders is a world with an unacceptable concentration of power in one place. (Probably Washington DC, or Wall Street, and probably NOT Brussels, or Geneva.)

The recently independent countries of the world (i.e. which have been liberated from western imperialism since WW2) naturally want to reap the fruits of that newly-won independence and sovereignty.

In particular they want (and deserve) 100% sovereignty over their natural resources and to earn 100% of the revenue earned from the extraction and sale of those resources. In all-too-many such countries, the resources are extracted by western-owned mining or energy companies who keep the lions share of the revenue. This was the mainstay of the old European empires - and it continues to be the mainstay of the current US empire. It should be unacceptable in our modern world. But the 3rd world and non-aligned bloc see globalism as a stalking horse - or rebranding exercise - to perpetuate the old imperialist order.

In a most egregious example, the Anglo-Persian Oil Company (now called "BP") extracted vast amounts of Iranian oil to fuel the Royal Navy's (then) vast fleet of battleships. BP was able to keep more than 80% of the revenue (which ultimately came from the British taxpayer) while Iran had to be content with less than 20%. It was nothing short of robbery! Whenever the Iranian leadership complained, a Western-backed “regime-change” ensued. When Iran finally decided to keep all the oil and all its revenue for themselves, they were demonised and condemned as being part of the "Axis of Evil".

What is needed is a world wherein power is more-or-less evenly distributed across manageably-sized units (called "sovereign nations") who are all entitled to 100% ownership of their natural resources and the revenue thereof - but no more.
