And then are immediately 'disposed of'. That is, quite literally, a fire-and-forget problem; those electronics don't have to keep working for months or years.
Yes but they do have to keep working after those 50,000G. Which is the thing: provided they survive acceleration, the remaining problem is cosmic rays. But we're talking about such small craft here that we'll be able to launch literally hundreds, probably thousands - the real challenge is getting the 100GW laser array built. Once you have it...no reason not to use it.
Similar to XorNot, I don't really see the mechanism by which high acceleration could substantially reduce long-term reliability of the solid state electronics without breaking them completely.
