This makes me wonder: are there "cloud drive virtual sneakernet" systems that will communicate e.g. by a client uploading URL request(s) as documents via OneDrive/SharePoint/Google Drive/Baidu etc., a server reacting to this via webhook and uploading (say) a PDF version of the rendered site, then allowing the client to download that PDF? You effectively use the CDN of that service as a (very slow) proxy.
Of course, https://xkcd.com/538/ applies in full force, and I don't have any background in the space to make this a recommendation!
It doesn't apply imo as OP is probably not a high value target of the govt, he just wants to bypass his govt restrictions and I doubt the situation is so bad that the govt will send people physically to deal with people circumventing the block.
Your solution could technically work over any kind of open connection / data transfer protocol that isn't blocked by the provider but it would be an absolute pain to browse the web that way and there are probably better solutions out there.
How about IPv6 over S3?
