There is an existing lawsuit fighting over the legal mandate to enroll in Medicare upon age 65; the rulings so far are that you have to sign up for Medicare when you take Social Security or you can opt not to use either, but there is not either/or of SS but no Medicare or Medicare but no SS.

You are wrong.
I have MANY clients who do not draw Social Security yet ARE on Medicare Part A AND Medicare Part B.
Likewise, I have a client who did not take Medicare Part B until he was over 80 years old, as he continued to work until then, but he DID draw Social Security for many years before he took out Medicare Part B.
Please do not post nonsense, this is serious business.
I do this for a living and you should not advise people
