Just from talking to people I think it's not an insignificant psychological hangup for people considering buying EVs. Whenever I discuss this with folks, it almost always comes up, if not just writing it off because charging will be a struggle, they may have considered possible solutions to this, but it always comes back to 'will this be sustainable for me long-term'. Nobody *wants* to replace a car that they like and enjoy just because they can no longer fuel it conveniently. You're never going to have that problem with an ICE or hybrid in the near future. Personally I absolutely *loathe* the process of buying and selling vehicles. It is painful on both ends, used or new, and when I buy a car I expect it to last me 10 years or more. There's a bit of a mental block to get over for people who have traditionally owned ICEs, and this is just one factor of many that goes into it. Fundamentally I think it is down to a lack of feeling of control over their freedom, if they can't control the charging. It's well and good to say 'well if your employer's parking lot decides the EVSE isn't profitable and rip it out, you can just buy a new car or choose to leave it parked for a few hours at a chargepoint once in a while! NBD!', but I don't think that really does anything to convince people to buy it anyway.
It's clearly a real psychological thing, but it isn't rational. People buy and sell cars all the time, virtually everyone I know has had multiple cars in the time I've had the same one. Circumstances change, maybe not availability of fuel but people have kids, kids grow up and move out, they change jobs, buy or sell a travel trailer, boat or other thing and either need something bigger to tow it or no longer have a reason to be commuting in some huge thing. Gas prices rise and smaller cars become popular, they fall and massive SUVs are everywhere. Seeing this constant churn I just can't buy that most people have a big hangup about changing cars, they do it all the time, for reasons far more trivial than not being able to get fuel. it's just another irrational way of convincing themselves that something different than what they're used to won't work for them.
Some people DO avoid it, I mean I drove the same $500 car for 17 years and it was still in nice shape when it got totaled but I'm an edge case. I have multiple friends who went through at least 4 different cars in the same period I had that one, most weren't even due to a pressing need, just because they wanted something different.
