as lawrence alluded, anarchists don't believe in "dissolution of the constitution" because, for one thing, that would require a body to dissolve it and that body of people would be representing other people, and representation means that people are not doing for themselves (to be simplistic for the sake of this example). ignoring the constitution, as it is a document of state-craft, is more what anarchists (would) do.
some anarchists just want government and capitalism gone, and define those in more constrained ways (ie, government = people with a certain amount of power; capitalism = individuals at a certain remove from production who yet control production). other anarchists see capitalism and the state as philosophical and psychological constructs as much as material ones, and believe that we all participate in those constructs and so we all need to change before anarchy can actually happen sustainably.
bolo'bolo is a good (not perfect) idea of how it might work to have many different people living in different ways that are on some level compatible.
it seems to me that the most practical anarchists are the least visionary; imagination suffers when people try to figure out steps for how to get from where we are now, to where we want to be.
what kind of anarchist one is probably depends a lot on whether one thinks that creativity is more helpful than practicality or vice versa.
this site tends to err on the side of visionary, and it sounds like you're more interested in practicality. that could be good for both of us, but is more likely to leave all feeling dissatisfied. :(
it would be great if they weren't so opposed.
