Better than anarchy and better Palestinians divided between Hamas and the PA is fair statement. Most Israelis don't believe any Palestinians have an interest in peace (I don't have a survey handy but I'm sure we can find one) and their actions reflect that belief. But if you can make a reasonable argument how defunding Gaza would result in peace then I'd be interesting in hearing it.

All that said, the actions taken by the Israeli right are certainly not helping the possibility of a future peace agreement, but it's not clear whether this specific action belongs in that group. One might argue that a stronger central authority in Gaza means there is a partner for a future agreement and that if Gaza can transition to be a more peaceful place (and it seemed to be heading in that direction) that would also support a future agreement.
