That access is permissioned. As long as you use an ISP, there is no way around it.
No matter the anonimization tech you use, you always need to announce an "entry IP" which can get blocked.

So you doubt an end to the open internet will ever happen?
If it did, it would be so different enough from the current internet that still calling it "internet" would be incredibility misleading.
I'm talking about infrastructure. We would need a parallel infrastructure to be independent from ISPs.
If a combination of HAM radios, wifi mesh and consumer drones can create a rival parallel network, it would not make sense to still call it "the internet"
