We do need altcoins that play its role in daily payments and minor to major things in human cilization, bitcoin in contrast plays as a leader and backbone of crypto currency and blockchain industry.
You need an altcoin specific thing or maybe a side chain, ethereum had to split it's chains up afaik to offer people an option to download just the main chain or the smart contracts chain (because there's a huge difference in the size)... The more you try to put into a chain's function, the lower it's security will be but separating things up is a great way to get around that problem into altcoins and side chains. BSV doesn't have much going for it so this is probably a good way to repurpose the coin - but I doubt bsv has many nodes.
