It's pretty much impossible to cut anything. Can Black separate White here?

Actually, I would rephrase that as "... a game between competent aggressive players, the majority of the board would end up as a seki." It is possible that both sides would concentrate on their respective eyes first, then try to connect everything on the board to them.
It is very hard to make eyes. If you want an eye in the corner the 2-2 point is your only move, but trying to protect the 1-1 point can kill you.

This might be a decent candidate for "crazy go" night at a Go Congress. Though I wouldn't be surprised if it has been done before.

Some other crazy go variants. In each case, it's regular go, except with an extra rule:

Variant 1: Each player's move cannot be directly adjacent to the opponent's previous move.

Variant 2: After each move, you may choose any point on the board and forbid the opponent from moving there on his immediate next turn.

Variant 3: After the first N moves by each player for some small N, such as 10, every subsequent play must be a knight's move away from an existing stone of your own color. (I've actually tried this one several times, and it's pretty fun - midgame fighting and life and death are weird, but surprisingly much stuff still works, such as ladders, extending cutting stones, hane-at-head-of-2 shapes, etc. By the endgame, most normal moves and sequences will be legal.)

Variant 4: Redefine liberty: of the 8 neighboring fields of a stone two (or more) adjacent fields (in the conventional understanding) must be empty to form a liberty.

Suggestion: :b3: forms a connection with :b1:. Now :w4: no longer connects to :w2:, as it would have to cut across the black connection.

I believe a game using this idea already exists and uses line-shaped pieces to indicate connections.

Twixt is one example, using knight's move connections.
