Whatever one may feel about Jagger's remarks, antics and refusal to gracefully exit the public eye in his advancing years, it really makes no sense to call him a complete loser.
Anyone who has made as much great music (even if his best was decades ago), sold as many albums over so many years, earned hundreds of millions over the course of his lifetime, bedded many of the hottest women on the planet, gotten himself knighted, can still sell out concerts even decades after his best is behind him, is still in physical shape to to what he does at his age cannot POSSIBLY be a loser if that term is to have any meaning.
A cad, a jerk, a miserly, preening, narcissistic, self-important, uncaring, debauched pig of a human being, possibly.
But a LOSER? I think not.
If the effects of one's life last no more than a generation past one's death, that is a loser.
Before I get hate mail...even if all you do is contribute to the raising of your children to be better people, who in turn inspire their children, you are not a loser. On the other hand, if you spawn demon seeds and waste your life in leotards, you are a loser.
The Stones inspired a drug culture. But, they never really inspired a musical change. Almost everything they did was ripped off from somoene else.
