For my family's email needs, $12/user/month is a bit of a non-starter given the competition.

Your preference to travel could be understood as imposing a negative externality on those you contact while travelling (in the event you were infectious at the time). If so, I think an argument of why you are taking precautions to make your travel safer (for others) might be more persuasive or thoughtful than a mere statement of your preferences.
If your preference approach is applied to other negative externality actions (like smoking in restaurants, driving much faster than others) the argument seems weaker .... your “I just like to do it [impose costs/risks on others]” rationale has the risk of appearing selfish rather than empowering.
There's another possible contributing factor: government can offer higher future pensions without increasing current expenditure (because government is not forced to fund the higher pensions until they need to be paid, many years in the future). Maybe that's why so many US states have dramatically underfunded pension plans (meaning teachers and other pensioners might not actually get their promised pensions when they retire).

My experience is that if there's a new statistical method developed, it will be often be implemented in R first. (This may be more true for statistical methods than machine learning or other fields).
I don't think there's quite such a wide range in the Python ecosystem yet (although it is rapidly growing, and is definitely a better choice for certain analytics situations).
None of this is to say that you necessarily lose anything other than convenience by using other languages eg Python for modelling.
