I agree with you. There has never been a point where x amount invested in Bitcoin is pointless. Whether $10, $100, or even thousands of dollars invested all still counts. It is a game of accumulation. No successful investor was able to achieve a good portfolio by buying Bitcoin once. And most of them did not start buying with a huge amount. They started with whatever they had then and now their portfolio looks good for the long term.
Any amount is ok as long as you purchase in such a way that network or gas fees are cheap and enough to cover your expenses. We should not compare one step to another man's step. The financial capabilities are different yet it shouldn't be an excuse that one should fantasize about buying Bitcoin and not doing that at the end.
Every amount of Bitcoin that we collect will of course be very meaningful for us to invest until we can get profit from what we invest and maybe only some people can accumulate Bitcoin in amount but starting with any amount we have as you said is also very good and we will be able to get profit from what we have invested when the price increases later and I really agree with you that we don't need to compare the steps we take with those taken by others of course this will make it difficult for us when trying to accumulate Bitcoin and we must be able to focus on what we do and of course we continue to do it consistently in order to get good results from what we have invested.
