There is money for isolating people and a benefits system. If people are on low incomes they are likely already getting universal credit and it would reflect the lost income as well.
There isn't an excuse and teachers, nhs workers, supermarket staff etc shouldn't be being put at risk because people won't get tested.
The payments for those self isolating is only for those on means tested benefits. Even if you do get the £500, it's worth noting that it's noticeably less than minimum wage (£610.40 for 35 hrs pw). The discretionary payments don't exist outside England, and where they do and the criteria are published, the criteria are very narrow.
Many people on low incomes aren't eligible for benefits - for instance, someone who works full time on minimum wage, but who doesn't have kids, is deemed to earn too much for UC.
There's a built in 5 week wait for UC, so it simply won't kick in for two weeks of self isolation.
The result is that you get people in my situation - I'm self employed, so there's no such thing as sick pay, and I won't earn a penny if I self isolate. My income has been clobbered by lockdown, but I'm one of the 2.9 million people who have fallen through all the cracks of government support (see the #ExcludedUK campaign if you want to know more). I'm not eligible for any means tested benefits, so I wouldn't get the £500 payment.
So, the brutal reality is that I can't afford to self isolate, because it would mean losing two weeks of income in a year when I've already lost a five-figure sum in income, been totally abandoned by government, and have no idea when I might be allowed to work properly again - I work across several sectors, one of which is weddings.
No fucking way would I be queuing up for a test if I lived in Liverpool.
