I mean the sovereign answer is that they should run their own. The only difference with this solution is integration with another corporation handling some of the backend for wallet infra. Which is how products naturally scale. So I get it. I really do. It's easier and you're trying to get a product to market. A business is not an individual. It wouldn't make sense for them to make decisions like a sovriegn individual. But where is the line? When is is good/bad/indifferent to make certain tradeoffs? Is the decision not clear for primal to have Bitcoin in self custody for their Treasury? Maybe they should have ETF instead. It's the same thought process why a business would make that decision. The solution would be for primal to have their own lightning node. And it should be proportion in size to the users they expect to serve. That's really hard at scale though. I get it.
