Well danadc..If you had started accumulating BTC at around the mid-ranges the amount that you are currently suggesting, at $30 per week at around the time of your forum registration, then by now, you would be quite close to having 1 BTC. You would have had invested ar0und $12k and have right around 0.83227421 BTC. Pretty damned close to a whole bitcoin.
At the same time, I doubt anyone is suggesting that 1 BTC is enough, even though someone just getting started might not be able to realistically aspire towards accumulating a whole bitcoin in the next 10 years, unless maybe he is potentially starting at around $250 or more per week, and even then, from my perspective, he may well need to bet to higher levels of BTC buying if he expects to get to 1 BTC or more in 10 years.
For anyone, like you, who potentially has spent some time accumulating bitcoin, he would be factoring in how many BTC he had already accumulated, and hopefully after nearly years registered on the forum you would have had been able to accumulate more bitcoin than someone who is just currently starting, and yeah, sure it is possible that 1 bitcoin is even far from being reached even for a person, similarly situated to you, with nearly 8 years registered on this forum.
You are absolutely right, that those who have been investment Bitcoins in small amounts are far ahead of the newcomers. It is absolutely true that collecting 1 Bitcoin will be a little difficult for newcomers, in my opinion investment Bitcoins on time is the biggest key. If newcomers understand that if they can continue to invest in small amounts, they can expect good things in the future. Collecting 1 Bitcoin will not be easy for newcomers, but nothing can be achieved without effort. I started investment Bitcoins little by little, I have not collecting one Bitcoin yet, but I have not given up. If you can collect Bitcoins consistently, it is possible to go a long way.
In as much as I would like to say you are right I would also want you to understand that it is not just about investing in Bitcoin on time but rather it is about consistency and determination, there are people who started some time ago but right now they are finding it difficult to continue investing so if anyone should start they should be willing and ready to invest regularly because only then can they have a good Investment portfolio. Lets be realistic here, getting a Bitcoin is not easy for newbie only even some mid or old folks are still finding it difficult to aquire that..., but I believe with good discretionary and exercising all the necessary things ( activities ) will be great in our investment.
