Yes, I realize all this. My question is how you can have such a system and still keep UI thread synchronization without having the opposite problem of marking all your synchronous methods.

in a strict language? I don't think it's possible. Because if you take a better look you'll see that it's not enough to mark functions as sync or async since inside the functions each line of code can be considered a synchronous function in it's own.
What you want is something like Haskell that's lazy and its not about "executing statements" but rather "evaluting expressions".
