My country blocks it.

Maybe you can put decorations (like fake spiderwebs or smiley pumpkins) on the hedge. You could also try putting up a sign with an arrow that points to the entrance...

Right clicking on a stack in your inventory separates the blocks.

Wait until the rest of the players run out of blocks, then tally the score.

try using animal transport.co.uk, but first make sure you know the exact address to send it to or your animal may get lost.

The "setblock" command places blocks, including air"blocks", so "setblock minecraft:air [x] [y] [z]" (without the quotes) should remove a block, or actually replace by air.
