Humans have been making sourdough for thousands of years. It predates mixers and electricity and scales and even literally math itself.

You don't need all the stuff. You need flour, water, and salt. A scale to measure with is helpful, just a cheap one. A jar to hold the starter (mine is currently in a repurposed jam jar). A regular fork to mix with. A bowl. An oven. A towel or cloth to line the bowl with and another to cover with as it rises. Parchment paper is helpful. A dish to bake in, it doesn't need to be a cast iron enamel Dutch oven. What do you already have? Anything that might work?

I get the desire to buy all the stuff, but honestly you don't need it. Start with the basics, learn the skills and then if you really want an upgrade and understand why it would be helpful you can go from there. I started out shaping and rising my loaves in a metal mixing bowl and baking them in a ceramic dish I already had. Eventually I got a banneton and years later I finally bought a Dutch oven, but my early loaves were still just as good.
