Much you say here is true, but with qualifications.  I live in a pretty small village, but my bug out location is carefully selected, and stocked with a year or so's worth of food.  I actually already have guerrilla gardens going there, naturalizing fruit trees and some staple crops so they blend in with the environment.  

Pasture is a good way to hide wheat or other staple grasses.  Trees can be great places to tuck in some berry bushes or fruit trees.  Potatoes, carrots and the like can be stuck wherever other herbaceous growth is ongoing.  Given a murderous government, like committed the Holodomor, it's extremely important that food production is concealed.  Never plant things in rows in a guerrilla garden.  Indoor agriculture can be a solution in a concealed shelter, but providing power for lights can be problematic.  Solar panels are far too visible, and so are windmills, but hydro can be well hidden and also may be productive of more power for the expense.  Suitable sites are far less available when dependent on hydropower though.  

There's a few folks quite local to the site, and good people, although I don't interact with them much.  I reckon when the time comes, that interaction will develop as necessary, and there's no need to poison that well aforehand.

A bit of planning ahead to make the bug out potentially permanent if necessary is not that hard to do, particularly with solar, food forests, and aquaponics tech nowadays.  Folks that just make a comfy hole with some food in it hidden away aren't planning for the gamut of events that could make them want to bug out, and I hope I have.

I recommend the kinds of things I have done as part of the prepwork to folks.

Also, bugging out will never work permanently.  Nothing lasts forever, particularly not us.  Bugging out will buy time, though, and sometimes the most important thing to have during emerging events is time to figure out WTF is happening and decide what to do about it.  The alternative is generally not as useful, although shooting first and asking questions later can buy time too.
