I was coming in here too describe this math as well lol.
Worse still is your speed wouldn't even be that far and you still need to sleep and eat and stuff.
Youd be at this for a couple months at least.
It would be great to cover all your small purchases though.
The best way to handle it would be to stand on something on have them fall and pull the rest out with gravity. I think that'd work. Maybe into a bag of holding.
If you wished to be a billionaire it's 31 YEARS. At $1 per second. No sleeping, no eating, no bathroom breaks, no nights off. 24/7/365. Realistically you'd die before your wish came true. Billionaires shouldn't exist.
I did a variant of a druid's yoke for a dragon chicken one shot. It was a chicken bib that when touched turned the wearer into a chicken. Scratch attack, 1 dmg. Anyone touching it would turn into a chicken. If you used tongs or a stick to remove it everyone changed back.
