First of all, an artificial tree is a lot easier to maintain, and it doesn't need any water, fertilizer or sunlight; all it needs is to be cleaned once in a while.
An artificial tree does not need to be cut down as it will always stay the same size. We all know how regular trees can overgrow your home and create undesired shadows, and something like that will not happen with an artificial tree.
Artificial trees can be planted everywhere. The climate doesn't matter; you can have palm trees in Alaska if you want it (although it might look a bit out of this world).
There will be no problem with insects and other animals. You have to be unlucky before your artificial tree becomes the nest of a disgusting bug colony.
Finally, you can quickly move your tree around if it's not too big or even packs it away for a few months. When they carry them, people bringing their trees with them are not unheard of.
Most artificial trees look very lifelike, but for the ultimate experience, it might be desirable to go for a preserved tree. While artificial trees are normally made of plastic, a preserved tree is made of natural materials around an empty trunk. The raw materials will even make the artificial tree smell the right way.
