I say why not but only if incomes are divide by 2.5
Gold miner 29gold per minute
Selling food and wood 5g/m
Trade unit are more expansive and harder to protect, that why I think /2.5 it’s a good trade for trade with yourself. It can help against too much passive game or help to finish a game in 1vs1. When you push forward in very late game and you have 3/4 of the map the last 1/4 of map is very long to destroy sometime it can take more than half an hour.
This is something I proposed a while back as a rework for the feitoria. Instead of a trickle of resources, your own feitorias would work as an ally market but at much lower gold income rate. Like 20% or 15% lower than regular trade.
It would be useless in team games though
How do you destroy building with trash unit (cost only wood and food)?
Some game are 30min or 1hour longer only because, the losing player can build trash building(cost only wood) faster than you can destroy them.
TBH if there was going to be an enormous economic overhaul like this in the game, I would much rather see woodlines replenish over time, or fish replenish overtime, or just have way more wood on trees so they at least last longer and the whole map doesn’t turn into a desert through overchopping. This way you could just make more produce to sell at the market for gold in late game.
