Should I sell my sp500 shares to lock in losses I can write off on taxes and buy back in after the 30 day wash sale rule isn’t a factor?

I would get $1600 to write off, and would probably DCA my way back in with my around 30k in assets. Thoughts? Is there a reason not to do this beyond missing out on potential returns? Would plan on putting the money in a 4.25 high yield savings account. Thanks for your thoughts!
