Agreed. Supply chain issues are already a problem, Bill Gates is buying up farmland and not farming, the Climate Change Scam will have us eating vegetables and bugs.
The problem I have with the gardening idea is that you need a LOT of land to grow enough to supply just yourselves with enough food to live, plus in times of food shortages, how will you prevent your neighbors from stealing your crops?
I do canning, that's a good plan. So is having a supply of medicines, just make sure you use them in rotation so when shit does hit the fan, you aren't relying on medicine that's been stored for many years.
I have a really good power generator that recharges from a solar panel and can run almost anything for quite a while.
What do you think about the currency situation? That's coming up real soon and may be the first thing we have to deal with. Do you think that gold and silver is the answer? What about bartering?
On the gardening....we do all of ours in planters/pots, now that we are older and not as flexible as when younger..... So we only grow a few things now, but in a limited area on my deck and by the shed....but of those few items... we grow enough to last a winter, for ourselves when canned. Stringbeans, green and then red peppers, and tomatoes, spinach is real real easy but I only grow enough to consume summer long, not to freeze or can...things to make food taste better like parsley, basil, rosemary all do great in pots, so does garlic....even onion can be grown in a pot....
But lazy man way to can more fresh grown food is just buy it, then dehydrate it like you grew it yourself.... Like I just bought celery and carrots, and dehydrated them to go with my bought minced onion dehydrated.... Many dishes I cook require all three in the recipes.... I know, I know, that's all small stuff, and when SHTF happens cooking fancy dancy won't likely happen anyway....but I can't help it!

My sister buys frozen vegetables and dehydrates them and vacuum seals in jars, to add to soups and stews in case we no longer have use of freezers.
Just buy can goods, little by little if you have no where to garden... Buying things like your favorite already cooked jarred tomato sauce and boxes of spaghetti is quick and easy prep and meal.
As far as buying gold or silver, we have never went down that road....though we do have jugs of coins.... I've heard it is a good idea.
We plan to barter if shit ever hits the fan.... Wine, sugar, salt, and coffee, and dried cocoa (chocolate)
We have a gas generator that can almost run the full house...and smaller solar and electric charged doohickeys but we plan to get another generator that uses a different fuel or solar, so in case gas is hard to get the other may be used.... We have a water source, our well, with solar power pump and a river/creek 70 yards away, across a meadow....and all kinds of filtering things and purification stuff if we have to use river water.
There is no shortage of game for meat, right on my property. Turkey, rabbit, grouse, squirrel, deer, duck in the vernal pond....right now they are beloved creatures and we feed them....can't see us ever killing my baby animal friends, but if we had to, my neighbor, a hunter would do it for us.
We rotate medicines and food.
My sister who lived in Miami when Hurricane Andrew hit, began prepping after that...before she knew the word prepping....back in 1992, and she got Matt and I to begin such about 10 years later, after 9/11....we were slow to follow her and still are way behind her thorough prep, but she had to live a month and a half with no electricity, so she knew more about what she needed to prep.
I'm in the middle of the woods, few people. By the hundreds of more animal friends than people in these woods..
