I think it all comes down to how much you like shaving with one. Even the busiest of us somehow manage to scrap some time for the things we really like doing. We sacrifice sleep, we sacrifice meals, some people sacrifice family time (idiots, if you ask me) to get to do what they really want to do. Hardly any of us is busy 24 hours a day.
Bottom line - and please, please don't take this as a criticism, it really isn't -, if you can't find the time to do a little maintenance on a razor it's because you can't be arsed to do it. And it is fair enough. I learned this with my wife, we used to ski together until she didn't anymore. She didn't like prople skiing around her, didn't like it when the snow wasn't perfect.... I tried persuading her to ski again and then, one day, she said: listen, I just don't love it enough to deal with everything that's uncomfortable, or plain dangerous about it.
She didn't love it enough. That opened my eyes. I do love it, that's why I don't mind skiing in shit weather, dealing with shit snow or having to be constantly aware of sooooooo many idiots around me, on the slopes. I broke my shoulder skiing and I still love it.
I love maintaining and using my razor, thus I manage to find time for it.
