Both the student loans and the ACA were actively gutted by Republicans, so they are a perfect example of why getting Republicans out is beneficial to you. You want student loan forgiveness? Get rid of the Republicans that are blocking it. You want single-payer or socialized medicine? Get rid of the Republicans that are blocking it. Both have been introduced by Democrats, both were voted on along party lines and failed due to Republicans.
You are missing my point: you are only hurting yourself and your goals with that strategy. Voting third party only helps Republicans and isn’t seen as any kind of protest by anyone who matters. No one says you have to LIKE voting for either of the parties, but only one party is closer to your goals, is actively trying to achieve your goals, and has a chance of actually getting elected so your goals can be achieved.
Slippery soap all over the floor would complicate matters.
