If anyone is investing regularly in bitcoin, even if it is ONLY $10 per week, they may well be taking from money that they might otherwise spend on fun, food and/or entertainment, so I would not necessarily agree that the BTC accumulator/investor is not going to be negatively affected by his/her dedicating value into BTC, but there is some potential for deferred gratification, and so the idea is just not be drawing from funds that are needed for basic living expenses (and even from emergency funds) but the could still end up causing less fun and enjoyment to be had in the presence with the hope of greater gratification (and options) at some point later down the road, whether that is 4-10 years or maybe even quite a bit longer before the additional options are starting to be seen and appreciated and maybe even being able to start to draw upon some of the additional options that start to materialize later down the road (and not even guaranteed, either).
It is true that by following your wise advice, if someone invests any amount in Bitcoin that he/she can afford, even as low as $10 on regular basis, can potentially have positive impact on financial future transform the financial future, if done consistently overtime. By waiting Bitcoin to reach a significant value such as, 0.5 to 1 Million dollars, which is attainable in the next decade due to scarcity resulting from halving events, and increasing demand from major financial institutions.
