You just find out you are living in virtual world (simulation) and was grant permission to freely create matter. You can create anything, as long as you know it. The admin use you as test subject and see what happen if you have that such ability.
You have 2 ability:
Inspect the item: the item is near you, in your eyesight, or you can touch the item with your body part (no need eyesight now). Then the item property, material, schema, ... is written in your brain.
Create a item: create a carbon copy of what you inspect (copy a dollar bill), or you can create new stuff with your creativity (got to start somewhere, scan some basic material like sand, water, ... first then build with basic material)
So, what should you do ?
Others "thing", law of physics, people/biology behaviours as normal.
I will duplicate paper cash.
Technically, it is fake cash, because serial is duplicate.
But in term of material, it is as good as real cash. I just need to acquire enough real cash with difference serial number, then it would be good to go.
Oh, and I will find a job where I receive payment/tip in cash, which harder to track my money flow.
I work like 3 years, slowly deposit my cash into bank (because you can only buy big stuff with money transfer, not cash), lie (increase my income/tip) on my tax report to PAY MORE TAX (so it is easier to put more cash into bank, transfer dup money into real money), buy bitcoin with cash, then occasional transfer into legit market, dump into bank money.
Move out of city, go to rural area, buy a lot. Retire.
Nobody know about my ability, not my wife or child. Remember, they are simulation agent like me. They are not real. Me include. So, don't fuck yourself up, take it easy life.
This is a great idea, although I'm not sure how the gold circulation control works. Don't you have to reveal where did you get from etc.? If not then this is the perfect plan.
Go to a museaum, copy an old Greek or roman gold coin in your pocket. Go home, copy many more gold coins. Go to a shipwreck or ruin, dig a bit, produce the coins and voila!
I hope you can get to keep them thought instead of archeological offices. Maybe checkout country policies first.
