The 27-year-old Miami Heat superstar said he is already looking forward to 2016.
"If I'm healthy, I did the math and I'll be 31, and if I have the opportunity to be out there, I will do it," he said. "I love it. I love being a part of it and representing my country. I don't know what may happen in four years, but it would be great to be back out there again. Definitely."
Since winning the gold medal in London, James said he has not heard from any members of the immortalised 1992 Dream Team, who scoffed at the idea that this year's US Olympic team could beat them.
"Nah," he said. "I don't expect to hear from any of them."
James was the US team's best all-around player in London, doing whatever coach Mike Krzyzewski needed while leading the Americans to their second straight gold. He was virtually unstoppable, just as he was in carrying the Miami Heat to an NBA championship in June.
In doing so, he silenced those critics who wondered if he could ever win the big one. James is on top, and he plans to stay there.
"I want that feeling again," he said of winning his first title.
James does not know if being a champion – and the only player other than Michael Jordan to win an MVP, an NBA title and Olympic gold in the same year – will change the way he is viewed.
Since announcing his decision to leave Cleveland as a free agent two years ago, he has been cast as the villain, reviled outside South Florida perhaps more than any athlete in memory. "I don't even get involved with that anymore," he said. "I don't look for it. I don't shy away from it. I just kind of roll with what's going on.
"For me, and it started before last season, I came in with a different mindset and a different attitude and it didn't matter if you believed in me or not, I was still going to be how I was and stay true to who I was and who I am.
"And that's all that matters."
