I'm sick of the left's "You're on your own" obsession, but I'll bite.
"You're on your own" is a MUCH MUCH MUCH better thing to hear than: "I'm from the government and I'm here to help you."
That
depends entirely on one's particular situation, as I once dared to hope was obvious.
Also, "You're on your own" general means "Freedom and Free Markets are better than serfdom and Central Planning, so I won't impose the latter on you."
Which is, of course, a false dichotomy and the people saying it know it, even if you don't.
