As someone with few USBs available, Ventoy takes me 2 minutes to flash, several minutes to copy a set of ISOs, and then any time I need it, it takes 0 minutes to have a working USB with some arbitrary ISO. Sure, it's not up to date, but I don't need it to be if I need to recover an install or use some random tool.
Defcon is a useful resource for networking and learning. It being run by and for good guys doesn't mean bad guys don't find the event useful. The vague risk of "getting caught" is probably worth taking, regardless of whether that risk is tangible, especially if they follow proper security practices.
I don't think you fully understand right to repair.
Companies (most egregiously Apple, but Samsung, Microsoft, and other tech, farming, and medical companies as well) have been actively introducing barriers to self or third-party repairs for decades. Apple serializes their displays on iPhones, so if you were to swap the screen on an iPhone without Apple's authorization or without specific hardware, your iPhone disables specific features on your new screen, even if it's a genuine Apple part. Apple also has incredibly unfair and invasive contracts with their authorized service providers such that they have to provide a slower return window than Apple's own service centers. Furthermore, Apple et al. don't sell every part needed to fix phones, and even when they do sell parts, they are often sold as packages or bundles that make the parts unnecessarily expensive.
To be clear, it's rare for companies to ban third-party repairs outright. However, the vast majority of device makers artificially limit who can buy spare parts and who can fix their devices via software, by tight supply chain control, lawsuits, or getting governments to seize the few parts that could be obtained. This means that most third-party stores can't compete with manufacturers because they can't get genuine parts without becoming "authorized", and by becoming authorized, they can't provide a quality service.
You're ignoring the fact that it's nearly impossible to implement this right now. Big pharma and numerous politicians want to keep the status quo for as long as possible. By the time we have more affordable medicine, numerous people would have suffered greatly or died because they couldn't access the medicine they need. Having solutions that don't require an entire rework of the healthcare industry is necessary so that we can save as many lives as possible.
I should've said "anything math-heavy," but even then, it seems like switching fields or applications of math requires understanding a new definition of the same symbols, and a lot of that could be avoided with words.
