I think dropping should get back into era, mainly because trade tables aren't everywhere.
for example: You're in a base and your friend runs out of food and they cant leave the base or they will lose it. it would be simple to just drop them a couple hot dogs... but instead you would have to run to the nearest trade table house, find an empty table (which is nearly impossible at start) and then pay $21 to trade.
nobody will be getting scammed if dropping comes back, because the trade tables have already been implemented. It is way more ethical to have dropping and trading because you aren't always trading; you're giving.
