I don't have children yet, but if/when I do, I won't tell them that Santa is real, either. It's possible to enjoy the story of Santa without lying and telling them that he literally exists, just as children don't have to literally believe in fairy tales or any other fictional story to enjoy imaginative play based on them.
My mother used Santa as a behaviour-management tool (we used to hear 'behave or Santa won't come' from October!) and when I stopped believing, at 6, she reacted to my comments with 'if you don't believe you get no presents.' So I pretended to believe until 11, when she made a big fuss of 'telling me the truth' before secondary school and acted surprised when I responded very unemotionally to the revelation. (I'm another person who likes being an adult much more than I ever did being a child, and this sort of thing is part of the reason why.)
I found it confusing and a bit frightening that all the adults in my life and in the media seemed part of a great conspiracy, since I knew Santa wasn't and couldn't be real. I still enjoyed Christmas, but not as much as I would have if I'd been told when I first questioned it that he's not real, but he's a magical story that makes things fun for younger children, etc. I have ASD and am literal-minded and I know not all children would react the way I did, but it's definitely not something I'd ever feel comfortable lying to my own children about.
The 'Elf on the Shelf' is a whole new level of lunacy. Constant surveillance? Bentham would approve.
OP, do what's right for you and your family. If you're not comfortable with the usual Santa traditions, adapt it so that it works for you. None of it is compulsory.
