Yes, the OP claim was silly, because it stated that the ONLY reason to use BTC is for illegal uses. I then countered with the point that I've bought services from people which were not illegal (or anything close to it). Unless I am lying, this invalidates the OP's point completely. Perhaps he could change his statement to say a large use is for illegal items, but saying the "only use" is hyperbole BS.
And the claim has NOT been made that BTC is currently useful for the "average joe". It is not useful for him... today. Just as the internet was not useful to the average joe in 1995.
You remind me of a comic strip character called Mr. Logic in a magazine called Viz. Some UK people might get a laugh out of that.
Do you have autism? I am not trying to be rude, it's a serious question, because people with autism often get confused like you are.
Let me put it in a more simple way. Let's say I don't currently hold any Bitcoins. I want to buy a product or service. What am I going to do? If I am paying for it online, I would use my Visa card. I punch in the numbers on the website, and I am done. If the product does not arrive then I can put in a dispute to Visa and get my money back. I think it's a good system.
Now, why the fuck would I, instead of going through that simple process, go through the hassle of buying Bitcoin, try to find a merchant who accepts Bitcoin for the product I want, pay him, and then have no recourse either through a payment processor or the police if something goes wrong? Why the utter fuck would anyone do that? It's so utterly bizarre that anyone thinks they would...unless of course it is a product that isn't available through the usual (legal) channels.
Also, as to your second point, I was actually on the internet in 1995. It was a million times more useful than Bitcoin is now. It had so many uses, even back then, that the comparison is actually hilarious.
