Only if an employer wants you and will sponsor you for an immigrant visa. Just like the USA, we don't want people who can't support themselves. This is a big reason people voted for Brexit - to stop totally free immigration from the rest of the EU.
So you need to find a job first, with a company that wants your skills and can't find a Brit to do it. I know of a few American youtubers living in the UK and it's either because an employer wanted them so they got their visa, or they're in the air force and got posted over here. (There are still a few US air bases in Suffolk so that's where all the military ones end up living. There used to be a lot more in the days of the Cold War, with the collapse of communism 30 years ago that's less of a concern now, but the US government still thinks it's useful to have a presence around the world and we're happy to host them.)
Without a visa, you can come for up to 6 months as a tourist, but do not have permission to work. British employers get fined if they are discovered employing someone without permission to work. Ideally you need some much-needed skill that a British employer wants or you're not going to get the necessary visa that allows you to stay longer than 6 months. No, it's not easy.
