What's the use of FOSS solomining (e.g. Bitaxe) when the hash rate is so small?

This article, presented as a prompt for discussion, addresses a significant question within the Bitcoin mining community: what is the practical purpose and inherent value of engaging in solo Bitcoin mining using Free and Open-Source Software (FOSS) hardware, such as the Bitaxe, especially considering the extremely small hash rate these individual setups contribute? The implied discussion would likely delve into motivations beyond direct profitability, exploring aspects such as the educational experience gained, the pursuit of individual sovereignty and control, the philosophical contribution to network decentralization on a micro-scale, or simply the hobbyist satisfaction of participating directly in the Bitcoin protocol's core function. It seeks commentary on the diverse merits, both practical and ideological, of small-scale, decentralized mining efforts.
