Without a doubt the goal of getting one bitcoin is getting harder and harder, which is why for the people that are on the fence about bitcoin they need to start their journey now or they may never realize this dream of theirs, but as you say it isn't a must to buy that much bitcoin, people have made some basic calculations and if bitcoin is adopted by billions of people the average amount of bitcoin each person could have is very low, so even something like 0.1 BTC can be a huge amount in the decades to come.
It is really getting harder to accumulate Bitcoin because the price is getting higher and higher. Another factor that make it difficult to buy BTC is the inflation of prices of commodities but a regular employee's wage doesn't increase. The ability of a normal individual to buy BTC is deteriorating because of the economic factors such as price hike, salary cut due to working hours changes, etc. Instead of buying a few satoshis, people will choose to spend their money to bring food to their table.
High inflation is probably the number one problem that people are currently facing, because even if the price of bitcoin is more affordable than it has been in quite some time now people need to spend way more money on their basic necessities, this leaves less money available for saving and investing which makes accumulating bitcoin even harder, however I sincerely believe this is something that people must make an effort to do because if they don't they will regret not doing this when they had the opportunity to buy bitcoin for less than six figures.
