Sure. But let's look at where we are now. If you're blocked from viewing an account, you need to switch to a different account (possibly in an incognito window rather than adding the account?) and explicitly load the tweet in question.
Hold up, how does the blocked person even know about the tweet? That should be an indication that we're not talking about reality any more.
The purpose of the block button, which Elon still doesn't understand, is to remove your posts from that person's algorithmic feed. Make it so that they don't get exposed to or notifications about your content, at least without creating a new account (not much you can do about that).
Why does that matter? Harassment. There are tons of people on Twitter, with large followings, that dunk-tweet or otherwise harass people, and in doing so end up triggering a brigade. If you've ever had the misfortune of being the victim of one of these negative engagements, you would understand how much this sucks. It destroys usability of the app as you have to wade through literally hundreds of cheap variation of middle school insults just to find any legitimate content.
You can't block the hordes of marauding masses, but if you block the key instigators, the problem goes away. They can't interact with you or subtweet you, yes, but they ALSO aren't notified of the things you say, and therefore aren't likely to spread links to your content in private group chats where this trolling behavior is organized.
You can autistically insist that akshully the block feature doesn't prevent someone from jumping through some hoops to view your tweets, but that's missing the point. It still solves a real world problem in its current form.
