The block limit was purposely implemented for spam protection
This claim has is just one of the pieces of unsupported nonsense pumped out by paid shills, it's so sad that so many people have just accepted it because of the number of sock accounts that have constantly repeated it.

As far as the thread goes, many people have made similar claims before. Their proposals have inevitably turned out to banal rehashings of more or less obvious ideas that the Bitcoin community considered and rejected as far back as 2010 because they don't respect some critical element of what makes Bitcoin Bitcoin that the proposer themselves wasn't aware of as a result of so much bitcoin promotional material giving an incomplete view of the system. The most common things I've seen such proposals do is introduce unfounded third party trust (usually in miners, sometimes in other random node operators) and in doing so eliminate the system's trustlessness.
Regardless, instead of saying that you have an idea that achieves some grand effect, you should simply publish the idea. Crowing about it just burns your and everyone elses time without making the world a better place or having an opportunity to improve your understanding.
