It definitely sucks to some degree, but it is the same kind of change when going from a small town or a rural area into a big city.
The houses where I lived in Canada weren't locked, they didn't even have locks. In Amsterdam it would take about 6 seconds from the time you left to have your house burgled if you did that.
As far as it reduces your ability to tweak or repurpose your software: I don't think that it has to be that way but it will definitely be harder than in an environment of trust.
Maybe there is an easy way to get both ease of fiddling and very high security but I haven't seen anything like that yet. There are some interesting research projects revolving around 'capability based operating systems' and such, maybe that's where they key lies, or in some other development currently underway.
