Yes. Climbing with a rope makes you climb more dangerous areas. You plan for falling (which comes always with a risk involved).
When free solo, you do not. So unless you literally have a death wish, you climb way below the level, you would do with a rope.
Even walking down stairs is dangerous if you don't master it. That's why we don't let babies close to stairs: they could kill themselves.
But an adult is so confident at using stairs that they don't consider it a risk anymore. Not that accidents never happen, but that is a risk that we are all willing to take because we "master" stair-climbing.
I see it similarly for free solo: one can master it to the point where climbing a route is fairly safe. It would be extremely dangerous for most humans, but for those, it is not. It is still risky, of course, but then some people die skiing slowly on-piste, and we don't say that it was "suicide".
Obviously, some people will take more or less risk when free soloing. But some people take a lot of risks while driving, and we don't say that "driving a car is equivalent to suicide" for most drivers.
The other sports that have no safety features and may look risky would be cliff diving and free diving.
What you list are activities that have risk. But in all of these activities there are considerations to implement safety to preserve the participant as much as possible. Most of these activities the participants have multiple layers of safety in case something happens in order to minimize the risk. Sky diving, Nascar, Plane Flying, Space exploration, deep sea diving, all prepare for the worst and implement safeguards to minimize it. The risk is continually minimized.
Of the activities you list, trad-climbing/sport-climbing would be the free-solo equivalent. This the relatively safe method of rock climbing that most people participate in. There is still risk and people still die. But you can make mistakes and the safeguards generally protect you from death.
Free soloing is a level above that. In free soloing, the risk of imminent death is a feature, not a bug. It is embraced as the core of the activity. The only comparable activity equivalent I can think of to Free Soloing is wing suit base jumping, although even that is often done with backup safety systems, so it still puts it a tiny step ahead.
In other words, you could think of all those activities as something people choose to do DESPITE the risks, but free soloing is done BECAUSE of the risks. That makes it very different from other adventure activities.
It's also worth noting that the last two examples (drug running and coming clean to your mother-in-law) are just a matter of necessity and survival. While there's technically choice in both activities, it is only done as a last resort despite the risks, which put those into a 3rd category. They are usually involuntary activities.
