"The Poor can't afford to buy bad quality."
Ie. if you plan not to be a beginner forever, you'll be probably needing a better guitar after some time. Let's say that your first guitar costs this 100 $. Then, after a year, you have to buy another one because the cheap ones quality is not enough any more, and you find a nice guitar that costs 200 $, and buy that. After a while, you have to buy a 300$ guitar... and at that point, you have spent 600 $ on three guitars, when you could've gotten the 300$ guitar in the beginning - or better still, you could've gotten even a very good one for 600 $, instead of a cheap, a better and a good one at that 600 $.
I'd say buy a good guitar if you plan to be playing more than randomly. If you just want to play randomly, that'll be good enough as it'll take you years to actually learn to play by randomly plucketing the thing.

With a good guitar, it'll probably be more rewarding and more fun to be a beginner.
And if your interest dies out, you can sell the good guitar for as much as it cost you. Musical instruments don't lose their value, like, say, electronics does.
