Your problem is that you're starting with the conclusion you want to be true and trying to invent logic to justify it. That's backward, incompetent reasoning. That's not how people arrive at real-world solutions -- it's just how they hide from admitting when they're wrong. The only way to find effective, practical solutions is to be willing to let go of your preconceptions.
You need to take a closer look at your reasoning, then. Because you're also kind of fishing for logic to rule out magnetic boots. Magnets interfering with the electronics, for example. Inside a hard drive, the part of your computer that's the most sensitive to magnetic fields, you'd find magnets so strong you could suffer serious injury by playing with them (I still remember the bruises), that will hold your feet to the floor so hard you'd think you're on Jupiter. So magnets and electronics are certainly a problem, but not a deal breaker. For starters, electronics are usually shielded, space electronics more so.
And I've not argued for any conclusion yet. I'm arguing
against a conclusion that has not have enough practical evidence to justify it – namely that the fictional magnetic boots from the show would certainly be impractical in the long term, and in a way detrimental to the show and its plausibility. I like the show very much, and I haven't yet seen anything absurd¹ in it. I don't see how pointing out at the huge swatch of reasons that could make them practical in the real world, or at the very least the fictional world of the show, is inventing logic – their alternatives aren't perfect either, so when you switch the environment drastically, you don't exactly know what would happen, and what would be better any more. The show's environments are radically different from both life on Earth, and life in current spacecraft, so don't make the mistake of thinking you know how things will play out.
You are right. When a significant numbers of us actually get to work in larger space dwellings and craft for longer periods of time, we will certainly have to abandon many preconceptions. But that will be all of us. We'll experiment with many many possible ways to get on, some very unexpected. It's too early to exclude magnetic boots as an option altogether, we will root them out on their performance when the time comes. Not on our preconception that they wouldn't work, because of a dated experiment on outdated magboot designs and premises that may not hold in practice.
In the end, both the problems and the solutions would turn out very different from anything we had on the drawing boards (let alone scifi discussions on the Internet); many details will be vastly different from even our wildest expectations or what was depicted on scifi shows. Being conservative about it is a double-edged sword – you'd be the closest, but you'd miss all the surprises, particularly on how we make our environment more to our liking. Mag boots are kind of compromise between conservative and implausible – they make it familiar, but aren't immediately expected to be there. Again, if we find a way to walk in space (most likely due to making all long-distance spacecraft rotating), scenes with magnetic boots will look more plausible than scenes with everyone floating around all the time.
I don't like magnetic boots at all. I actually fear magnets, having your entire life on floppies does that to you. I refuse to buy things with magnets in them, like phone cases. But I do watch the show open-minded and am kind of annoyed of hearing how magnetic boots are silly and out of the question. In reality, we don't know that for sure, and I am willing to see ways that could make them much usable, and to my liking. And I certainly don't have to suspend my disbelief to watch zero-g scenes in the show.
¹ Well, after I did invent logic to justify the protomolecule, and I retroactively ruled it not absurd.
