Gates are too expensive for their rather niche use (non automatic low-tech ones needed)

A gate can be used to close off a path momentarily.

They cost:
- 6 planks (which is fine, elegant and fairly low tech
- 4 gears (for automation)
- and 4 scrap (for... the 2 hinges and 2 latches?)

Which isn't awfully expensive, but not that cheap either.

When you get enough stuff to spare, you might not need them that much, given that you have resources to spare for bridges and alike - allowing for 24/7 safe passage.

It is a similar pointless situation with beaver healing. Its so late, by the time you got it, you rarely, if ever, need it (other than mere convenience).

I suggest to either lowering the costs by the 4 scraps to make it more accessible without raiding far-away ruins.

OR introducing a "low cost" NON-AUTOMATABLE version that only costs wood:
- 4 raw wood
- 6 planks

Something like that.
To lock off dangerous paths early on - with the click of a button.
It could come with that nice button function the MANUAL SWITCHES have, so you can tie it to your UI and don't have to search for it.

Flood over? Tap - done!

Just let us fence off things without having to gather materials from around the map for such a nice use case.

I might as well pause the projects or just DELETE THE PATH, and that costs me NOTHING and goes instantly without a single beaver working!!
You see the issue here, right?!

"Free"vs "Sorta expensive" - for a niche case use.
