um….no.
a DNSSEC signed reponse will be something that can be validated to determine accuracy of the answer received.
that’s not the same as finding the source of what/whom is doing spoofing.

not quite;  you can also use your ISP’s DNS servers, or, run your own.

yes, considerably easier, than if you used your ISP, whom you, presumably trust.

that’s a broad statement, with little evidence.  from a pretty well connnected, dual-stacked host in JNB, i see: 
nishal@jnb:~$ dig +nssearch za | awk -F ' ' '{print $11, $12, $13, $14}'
194.146.106.78 in 0 ms.
204.61.216.55 in 1 ms.
2001:67c:1010:19::53 in 1 ms.
2001:500:14:6055:ad::1 in 1 ms.
196.4.160.27 in 3 ms.
2001:4200:ffff:a::1 in 17 ms.
196.21.79.50 in 17 ms.
2001:500:2e::1 in 170 ms.
192.5.4.1 in 179 ms.

for good measure, i also pasted in the results from a host in CPT below [2].  
all of this tells me that 1 host isn’t dual stacked (naughty 3741 !), and one host is likely hosted out of ZA.  i don’t see any of the IPv6 problems you allude to.
since there is no requirement to have all secondaries inside your country, and i recognise three of those hosts as anycast, i’ll ask again - what IPv6 problem are you seeing, and are you sure it’s not just from your perspective?
