Okay, as you yourself said, dismantled means taking apart. Here's a dictionary definition of it: https://dictionary.cambridge.org/dictionary/english/take-apa.... SSA actually is a great example of this happening, as the existing social nets are split into different parts and one-by-one parts are removed as to not cause a reaction from populace. This is why I previously mentioned frog boiling machinery, as it is a part of divide-and-conquer tactic. This is why I mentioned the first they came for socialists poem.
And if you read the article I linked, you would find there why this effectively removes access to it for some people. Some of the people in most vulnerable groups of population who need these nets most don't have access to reliable transportation and internet or struggle using devices to access it. It doesn't mean they don't deserve to have it.
SSA still exists, it wasn't dismantled.
You should go ask people who can't access it anymore if it was dismantled enough.
