Maybe we should set a real goal? For example, the number of full-nodes should be at least 100 thousand. After all, at 100 thousand full-nodes Bitcoin will remain decentralized? And then your terrible "every week a new hard drive" transforms into ~$5000 a year. If we have a billion users, how many of them can afford to maintain a full node for $10000 a year?
Call me after you've read what you've just written and realized you're not making sense at all.
These "most people are damn lazy and don't want to learn" calmly figured out Bitcoin, use a Bitcoin wallet, make transactions, and launched 100 thousand full nodes.
And when it came to LN, they immediately became stupid. Maybe they don't want to use LN because it's just a shitty system.

Again you're making zero sense and I have a vague feeling you're not here to debate but to impose a point of view, that starting with the stupidity of at first setting a goal which in the second part you claim it has been already achieved. So which one is it?
Besides you're not realizing one thing, hundred and thousands if not millions of those that currently use Bitcoin haven't installed a full client in their life, if the wave of people that started adopting bitcoin would have not used even a single time blockchain's web wallet their service would be here waiting for a decade anniversary. We're not even for a moment talking of the people who have used bitcoin till now, if we would talk only about them then what's the point of increasing the capacity as the bitcoin works pretty normal right now, we're talking about the future and in the future as it happens with everything the waves of people using something became less and less knowledgable as that things go mainstream. It happened with the first computers, it happened with the first smartphones, it happened with the first banks, it happened with the first book.
Next time either use logic when conversing or don't bother to do it at all.
