security - Do I need to set a wifi password if I live on large property? -

to reach wifi, intruder need come in fence , sit down next house. seems unlikely, i'm getting pushback housemates.

does not entering password potentially create easier for:

a hacker on net come in our network?

malware jump 1 of our computers another?

devices allow hacker pickup signals outside normal wifi range? wrote "with decent high gain antenna, can solid half mile range play in [instead of sitting in van outside house]."
