Delta will hit these places because an Underground Railway of sorts will form easily with porous borders.
Not what is showing if borders are closed tight, as opposed to letting workers through, say from Sydney to Melbourne, which sparked Melbourne's latest outbreak. Whether I agree that's a fair and balanced method, not the point.
Civil disobedience will spill out with no hope in sight. There are desperate people irrationally locked out, away from their livelihoods and loved ones. Everyday the hardship and hard luck stories are on the increase. A destructive political and social showdown is looming. How terribly sad.
The main issue with civil disobedience is just those that are not following the rules, which may account for 1-5% of the population, say 50,000-250,000 in Sydney or Melbourne. These are not the protesters or trouble makers, just those going out and spreading the thing within their community, this is the quiet growing number that is killing any chance of lockdowns ending before vaccination targets are reached.
The protesting minority is less than 0.1% of the population, strangely enough you are more likely to die of covid than attend a protest on "freedom". That said these individuals are having no real impact on lockdowns, and are just causing trouble and most likely pushing authorities to further restrictions, hence why most of the public think they are fools. The only effect they may actually have is make restrictions worse, mass protests and rioting just results in martial law.
The protests in Melbourne were an anarchists perfect dream, thugs rushing police, kids involved and getting sprayed, remember those setting these things up revel in that. Not whether you are free.
