It's an escape hatch. If they block outright, then if they block outright and are wrong, a legitimate user cannot see content that they have a right to. If they use a redirect, then a user - legitimate or illegitimate - can bypass that block, but they have to explicitly take action to. Consequences are on them, then.

Remember that Google's mission is to "organize the world's information and make it uniformly accessible and useful". Their purpose is not to block the content at all - if it were up to only Google, they wouldn't have either a block or a redirection, you'd just be able to access the content. The country redirects are the result of a negotiation with the country, where Google says "Okay, if we did this, would it be acceptable" and the government says "No, too permissive" and then Google says "Okay, what if we did this?" and then finally the government says "Alright."

That makes sense. However, how do you get past the block? Changing the TLD to com redirects me to gr every time.

I think that's what the ncr (No Country Redirect) parameter that the article talks about does - it tells Google to not redirect to the appropriate TLD.

That was for google.com, but it turns out that it works for blogger as well! Interesting, thank you.
