Just because Raleigh experienced some of the places and themes in Shakespeare’s plays does not make a coherent argument that he was the plays' author. Shakespeare also wrote about slavery, yet neither Raleigh, nor Shakespeare, nor any other name put forward as an author of the plays was a slave. He wrote about fools, jesters, philosophers, common men, women, aristocrats, nobles, royalty and magicians but in no way does that mean that he was any of those things.
A writer is not their subject. Tolkien is not an orc. Robert Louis Stevenson is not a pirate. Mary Shelly is not a monster. Therefore, Shakespeare need not be an intrepid traveller, statesman, or member of the aristocracy to have written his plays.
