The whole do your own work thing definitely seems to be a strong part of the motorcycle culture. But it's not me. I don't change the oil on my own car, either - and it doesn't diminish my enjoyment of it one iota. Would I save a few bucks doing it myself? Sure. But while I don't claim affluence to the point of generalized fiscal indifference to the cost of things, I can afford to professionally maintain the vehicles I own.
None of that is to pass judgment on those who enjoy working on their bikes - and I get that this is fun for some. I weirdly enjoy washing my car, where most consider that a pure chore. But mucking about with greasy bits and fiddling with wires is not my thing. Hopefully that shouldn't be too hard to understand even if it is your particular thing.
