Roundup is a systemic herbicide. You have a chance of killing the parent plant since they share roots. It probably won't, but it seems pretty drastic when you could just pull any shoots. You can even pot them up and give them to friends.
I think the best bet would be following recipes. That means finding recipes that minimize 'to taste' instructions. A lot can be done by look and texture, so you can be decent enough for anyone who's not a snob. Also, err on the side of too little salt and put some on the table.
You can look at wildlife/pollinator gardening. There are different focuses like rewilding or even restoration. There are also a lot of companies willing to sell incredibly invasive plants while calling them nice things, so buy from a reputable source if you do buy plants or seeds.
Refreezing is fine for safety (if you thawed it correctly). The main reason not to freeze and thaw things multiple times is that tiny ice crystals do damage to the structure of the food each time freezing happens.
In meat, that damage makes your meat dry out easier when cooking. That's normally a bad thing, bit it might actually be a good idea for making jerky.
In short, I would have no hesitation using refrozen meat to make jerky
I would do it from the top (flat) with a guide. I would probably start with a circular saw, go until the front bumps the wall and finish the last parts with another tool. This allows the front and top to look straight which is all you'll see
When someone would ask, "Who wants to be 100 years old?" My grandpa would respond, "Ask someone who is 99." I think that applies here. When will you feel like you can give up - well, why not now? What will be different when you're 40 or 50? Why wouldn't you want to be dating? Why wouldn't you want your body to work?

I didn't like the first wall example because the clicking cadence changes, but the field and trees were very clear
Reminded me of this 3 min "nature documentary" about the ibis/bin chicken https://www.youtube.com/watch?v=w4dYWhkSbTU
