Plans last until first contact with the enemy, as they say.
No one will know exactly how this will play out, and which preps are appropriate and which are unhelpful.
Hard to see how having more options & tools available is a bad thing. Just don't be attached to your possessions, realize they are just tools.
One of your best preps is to understand that a lot of what we "know", just ain't so. Be willing to ditch errors in assumptions.
Once things go down, it will be too late to call a "time out" and ask for more time.
I can't image someone in trouble regretting have too much gold/ silver. History shows that these tools have been used successfully to get yourself out of trouble.
