The problem with explanation “my subconsciousness just made it all up” is that there is no definition of what “your subconsciousness” means. If we are going as far as denying the existence of the entire universe, then even “well, then your subconsciousness would need greater computational capacity than the entire known universe” is not a meaningful objection, because the entire known universe, maybe even math itself, are just things your subconsciousness made up.
In other words, solipsism only works because you not-define the subconsciousness. Whatever objection anyone can make, you are free to expand your non-definition of “subconsciousness” to include it.
An equally meaningful philosophy would be that the universe is a cabbage. Not an ordinary cabbage, of course (please don’t strawman my supreme philosophy!), but a special magical cabbage, which magically has exactly those properties it needs to have in order to explain all available evidence. A universe-simulating, consciousness-containing cabbage. Can you disprove this?
Indeed, since there is no absolute distinction between the parts of reality that are ‘you’ and those that aren’t, then solipsism isn’t by itself a meaningful concept.
