Put a few drops of oil into the mug where it meets the canister. If the oil can seep past there, into the mug, add as much oil as possible. See whether you can twist the canister out.
If not: Chill the whole assembly. Get tools to handle the mug and canister. Heat the mug in very hot water, and pry it out. Twist as you pry.

Soak the mug in a sink of hot water to warm it up quickly. Be prepared to pry the gas cartridge out quickly, perhaps using small screwdrivers or needle nose pliers. The thermal mass of the gas in the cartridge will help slow it heating. Some shaking may help.
Then, don’t do that again;)!
It depends on the kind of camping you want to do.
The easiest type of camping to find is camping at a campground. Usually this involves paying a nightly fee (often around $20-30 per night) for a numbered, designated campsite. Usually the campsite comes with a fire pit and/or grill, a picnic table, a parking spot, and space to pitch a tent. Most campgrounds ...
There are no places in the US that meet your two criteria.
Gathering firewood is banded in most campgrounds. As seen in the related post, you can gather firewood in some very secluded locations, which will mostly exclude beach access.
