I would be very surprised if even a fourth of the list you just posted could fit inside the design contraints of tiny tapeout. You have about 1000 digital logic gates max as per their FAQ.
I don't think it's fair to knock it like that. This isn't going inside some industrial project. This is a hobbyist who went from zero(!) to ASIC.
It's a completely ridiculous list. The blogpost is about designing a 2 tap filter, not a CPU, so even if there wasn't a gate limit the design wouldn't have those things.
